From: Nicholas Mc Guire <der.h...@hofr.at>
return type of wait_for_completion_timeout is unsigned long not int, this
patch uses the return value of wait_for_completion_timeout in the condition
directly rather than assigning it to an incorrect type variable.

The return type of wait_for_completion_timeout is unsigned long not
int. This patch resolves the type missmatch by moving the call to
wait_for_completion_timeout into the condition.
This patch was only compile tested with: polaris_defconfig
CONFIG_SPI=y, CONFIG_SPI_SH_MSIOF=m
Patch is against 3.19.0-rc6 -next-20150130
