[PATCH] broken error path in drivers/pnp/card.c
The error path in pnp_request_card_device() is broken (one variable is left initialized and the semaphore is not unlocked). This fixes it (and has been tested). Signed-off-by: Jaroslav Kysela <perex@suse.cz> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
