[PATCH] i2c: mxs: match wait_for_completion_timeout return type
From: Nicholas Mc Guire
Date: Tue Mar 10 2015 - 14:12:46 EST
Return type of wait_for_completion_timeout is unsigned long not int.
An appropriately named unsigned long is added and the assignment fixed up.
Signed-off-by: Nicholas Mc Guire <hofrat@xxxxxxxxx>

Note that 4.0-rc3 does not compile for mxs_defcofnig due to a bug (typo)
in mxs-auart.c - the compile testing was done with the fixed up mxs-auart.
This was only compile tested for mxs_defconfig (implies CONFIG_I2C_MXS=y)
Patch is against 4.0-rc3 linux-next (localversion-next is -next-20150310)
