-Subject: [PATCH] ums_realtek: do not use stack memory for DMA in
- __do_config_autodelink
-
-__do_config_autodelink passes the data variable to the transport function.
-If the calling functions pass a stack variable, this will eventually trigger
-a DMA-API debug backtrace for mapping stack memory in the DMA buffer.  Fix
-this by calling kmemdup for the passed data instead.
