[PATCH] i2c: wmt: use msecs_to_jiffies for time conversions
From: Nicholas Mc Guire
Date: Sun Mar 01 2015 - 08:25:23 EST
This is only an API consolidation and should make things more readable
it replaces var * HZ / 1000 by msecs_to_jiffies(var).

Converting milliseconds to jiffies by "val * HZ / 1000" is technically
not wrong but msecs_to_jiffies(val) is the cleaner solution and handles
all corner cases correctly. This is a minor API cleanup only.
Note that the alignment is not exactly with the opening braces but rather
with the last tab-stop that will not result in going over 80 char.
Patch was compile-tested only for vt8500_v6_v7_defconfig
(implies CONFIG_I2C_WMT=y)
Patch is against 4.0-rc1 (localversion-next is -next-20150227)
