* ide: remove BUG() from ide_complete_rq()Bartlomiej Zolnierkiewicz2009-03-272-5/+7
| | | | | | | | It is no longer needed so remove it, also while at it dequeue the request only on blk_end_request() success and make ide_complete_rq() return an error value. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

| | | | | | | | | | | | Set rq->errors at ide_complete_rq() call sites and then pass error value to ide_complete_rq().

| | | | | | | | | | | | | | | | | | * Move request dequeuing from __ide_end_request() to ide_end_request(). * Rename __ide_end_request() to ide_end_rq() and export it. * Fix ide_end_rq() to pass original blk_end_request() return value. * ide_end_dequeued_request() is used only in cdrom_end_request() so inline it there and then remove the function. v2: * Remove needless BUG_ON() while at it (start_request()'s one is enough).
