Subject: [PATCH] i2c: wmt: match return type of wait_for_completion_timeout

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

Signed-off-by: Nicholas Mc Guire <hofrat@...dl.org>

Patch was only compile tested with vt8500_v6_v7_defconfig
(implies CONFIG_I2C_WMT=y)

Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
