| * usb-serial: fix usb_serial_register bug when boot with nousb paramDave Young2009-03-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With "nousb" cmdline booting, built-in serial drivers (ie. airecable) will trigger kernel oops. Indeed, if nousb, usb_serial_init will failed, and the usb serial bus type will not be registerd, then usb_serial_register call driver_register which try to register the driver to a not registered bus. Here add usb_disabled() check in usb_serial_register to fix it. Signed-off-by: Dave Young <hidave.darkstar@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | | | | | | Driver originally written by Qualcomm, but rewritten by me due to the totally different coding style. Cleaned up the probe logic to make a bit more sense, this is one wierd device. They could have prevented all of this by just writing sane firmware for the modem.

| * USB: Add platform device support for the ISP1760 USB chipCatalin Marinas2009-03-243-17/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the driver only supports PCI and PPC_OF but there are boards like ARM RealView where this is a platform device.

| * USB: EHCI: add software retry for transaction errorsAlan Stern2009-03-242-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1204) adds a software retry mechanism to ehci-hcd. It gets invoked when the driver encounters transaction errors on an asynchronous endpoint. On many systems, hardware deficiencies cause such errors to occur if one device is unplugged while the host is communicating with another device. With the patch, the failed transactions are retried and generally succeed the second or third time through. This is based on code originally written by Koichiro Saito.

But the sat to cypress atacb translation supposed the ->cmnd buffer wasn't modified. This patch makes it set the ->cmnd buffer after scsi_eh_prep_cmnd call. The problem and a fix was reported by Matthieu CASTET <castet.matthieu@free.fr> It also removes all the hackery fiddling of scsi_cmnd and scsi_eh_save by requesting from scsi_eh_prep_cmnd to prepare a read into ->sense_buffer, which is much more suitable a buffer for HW transfers, then after the command execution the regs read is copied into regs buffer before actual preparation of sense_buffer.

| * USB: serial: refuse to open recently removed USB Serial devicesJames Woodcock2009-03-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A USB-serial converter device is plugged into a system, and a process opens it's device node. If the device is physically removed whilst the process still has its device node open, then other processes can sucessfully open the now non-existent device's node. I would expect that open() on a device that has been physically removed should return ENODEV. This is manifesting itself with getty on my system. I do the following: 1. set up inittab to spawn getty on ttyUSB0, eg: T1:23:respawn:/sbin/getty -L ttyUSB0 115200 vt100 2. Plug in USB-serial converter cable 3. Wait for a login prompt on a terminal program attached to the serial cable 4. Login 5. Pull the USB-serial converter cable from the box 6. getty doesn't realise that ttyUSB0 no longer exists as /dev/ttyUSB0 can still be opened. 7. Re-insert the USB-serial converter cable 8. You should no longer get a login prompt over the serial cable, as the the USB-serial cable now shows up as /dev/ttyUSB1, and getty is trying to talk to /dev/ttyUSB0. The attached patch will cause open("/dev/ttyUSB0", O_RDONLY) to return ENODEV after the USB-serial converter has been pulled. The patch was created against 2.6.28.1. I can supply it against something else if needs be. It is fairly simple, so should be OK. I am using a pl2303 device, although I don't think that makes any difference.

| * USB: pxa27x_udc: add vbus session handlingRobert Jarzmik2009-03-242-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On vbus_session() call, optionally activate D+ pullup resistor and enable the udc, or deactivate D+ pullup resistor and disable the udc. It is intentional to not handle any VBus sense related irq. An external transceiver driver (like gpio_vbus) should catch VBus sense signal, and call usb_gadget_vbus_connect() or usb_gadget_vbus_disconnect().

| * usblp: continuously poll for statusPete Zaitcev2009-03-241-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usblp in 2.6.18 polled for status regardless if we actually needed it. At some point I dropped it, to save the batteries if nothing else. As it turned out, printers exist (e.g. Canon BJC-3000) that need prodding this way or else they stop. This patch restores the old behaviour. If you want to save battery, don't leave jobs in the print queue. I tested this on my printers by printing and examining usbmon traces to make sure status is being requested and printers continue to print. Tuomas Jäntti verified the fix on BJC-3000.

| * USB: usb-storage: increase max_sectors for tape drivesAlan Stern2009-03-241-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1203) increases the max_sector limit for USB tape drives. By default usb-storage sets max_sectors to 240 (i.e., 120 KB) for all devices. But tape drives need a higher limit, since tapes can and do have very large block sizes. Without the ability to transfer an entire large block in a single command, such tapes can't be used. This fixes Bugzilla #12207.

| * USB: gadget: fix rndis regressionDavid Brownell2009-03-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Restore some code that was wrongly dropped from the RNDIS driver, and caused interop problems observed with OpenMoko. The issue is with hardware which needs help conforming to part of the USB 2.0 spec (section 8.5.3.2); some can automagically send a ZLP in response to an unexpected IN, but not all chips will do that. We don't need to check the packet length ourselves the way earlier code did, since the UDC must already check it. But we do need to tell the UDC when it must force a short packet termination of the data stage. (Based on a patch from Aric D.

| * USB: add quirk to avoid config and interface stringsAlan Stern2009-03-243-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apparently the Configuration and Interface strings aren't used as often as the Vendor, Product, and Serial strings. In at least one device (a Saitek Cyborg Gold 3D joystick), attempts to read the Configuration string cause the device to stop responding to Control requests. This patch (as1226) adds a quirks flag, telling the kernel not to read a device's Configuration or Interface strings, together with a new quirk for the offending joystick.

| * | sysfs: only allow one scheduled removal callback per kobjAlex Chiang2009-03-241-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only way for a sysfs attribute to remove itself (without deadlock) is to use the sysfs_schedule_callback() interface. Vegard Nossum discovered that a poorly written sysfs ->store callback can repeatedly schedule remove callbacks on the same device over and over, e.g. $ while true ; do echo 1 > /sys/devices/.../remove ; done If the 'remove' attribute uses the sysfs_schedule_callback API and also does not protect itself from concurrent accesses, its callback handler will be called multiple times, and will eventually attempt to perform operations on a freed kobject, leading to many problems. Instead of requiring all callers of sysfs_schedule_callback to implement their own synchronization, provide the protection in the infrastructure. Now, sysfs_schedule_callback will only allow one scheduled callback per kobject. On subsequent calls with the same kobject, return -EAGAIN. This is a short term fix. The long term fix is to allow sysfs attributes to remove themselves directly, without any of this callback hokey pokey.

| * | Driver core: Fix device_move() vs. dpm list ordering, v2Cornelia Huck2009-03-244-5/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dpm_list currently relies on the fact that child devices will be registered after their parents to get a correct suspend order. Using device_move() however destroys this assumption, as an already registered device may be moved under a newly registered one. This patch adds a new argument to device_move(), allowing callers to specify how dpm_list should be adapted.
