pcmcia: cs: kill thread_wait
There is not reason to have a waitqueue if it's always the same thread that is waiting for it. Just use wake_up_process instead. Signed-off-by: Christoph Hellwig <hch@lst.de> Small modification: Also remove unused variable. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
