mISDN: Fix wrong usage of flush_work_sync while holding locks
It is a bad idea to hold a spinlock and call flush_work_sync. Move the workqueue cleanup outside the spinlock and use cancel_work_sync, on closing the channel this seems to be the more correct function. Remove the never used and constant return value of mISDN_freebchannel. Signed-off-by: Karsten Keil <keil@b1-systems.de> Cc: <stable@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
