Subject: staging: r8723au: Remove unused semaphores
X-Git-Tag: v4.9-rc1~119^2~912
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=243d38aab204bfd1c33ad6f412b654c9f7eed8cb;p=karo-tx-linux.git

staging: r8723au: Remove unused semaphores

The semaphores xmit_sema, terminate_xmitthread_sema, tx_retevt and
io_req have no users, hence remove all references to them.
Semaphores are going away in the future.
