return type of wait_for_completion_timeout is unsigned long not int. The
return variable is renamed to reflect its use and the type adjusted to
unsigned long.
Signed-off-by: Nicholas Mc Guire <hof...@osadl.org>

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
<w...@the-dreams.de>.
Patch was only compile tested with multi_v7_defconfig
(implies CONFIG_I2C_CADENCE=y)
Patch is against 3.19.0-rc7 (localversion-next is -next-20150209)
