[PATCH] i2c: cadence: match return type of wait_for_completion_timeout

[Nicholas Mc Guire <hofrat-Q945KHDl0DbYtjvyW6yDsg@public.gmane.org>]

return type of wait_for_completion_timeout is unsigned long not int. as
ret is only used for wait_for_completion_timeout anyway the type is simply 
changed to unsigned long.

Signed-off-by: Nicholas Mc Guire <hofrat-Q945KHDl0DbYtjvyW6yDsg@public.gmane.org>

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-20150204)
