Subject: [PATCH 2/2] staging: rtl8712: condition with no effect removed

The check for return of schedule_timeout() has no effect on the 
effective control flow of sleep_schedulable() so it can be dropped.

Signed-off-by: Nicholas Mc Guire <der.herr@...r.at>
---

The current codes return check for schedule_timeout() has no effect
and can probably be dropped unless it is intended as a placeholder
for some future change in which case a comment should probably be
added.

This patch was only compile tested for x86_64_defconfig +
CONFIG_STAGING=y, CONFIG_R8712U=m


Patch is against 3.0.19-rc6 -next-20150129 but depends on:
