From 7c2bb7aff9b5ef83c5b1fd3a9ef0af39bbbf1f7a Mon Sep 17 00:00:00 2001 From: Binoy Jayan Date: Thu, 2 Jun 2016 09:54:09 +0530 Subject: [PATCH] rtl8712: intf_priv: Replace semaphore lock with completion The semaphore 'lock' in 'intf_priv' is used as completion, so convert it to a struct completion type.
