return type of wait_for_completion_timeout is unsigned long not int. The
return variable is renamed to make the timeout condition clearly readable
and the type adjusted to unsigned long.
Signed-off-by: Nicholas Mc Guire <hofrat@xxxxxxxxx>
---
v3: rename the variable to time_left as suggested by Sergei Shtylyov
<sergei.shtylyov@xxxxxxxxxxxxxxxxxx> so that the timeout condition is
clearly readable.
v2: int ret is an idiom not only a declaration - thus rather than just
changing the type, rename the variable, as suggested by Wolfram Sang
<wsa@xxxxxxxxxxxxx>.
Patch was only compile tested with multi_v7_defconfig
(implies CONFIG_I2C_CADENCE=y)
Patch is against 3.19.0 (localversion-next is -next-20150210)
