Subject: power_i2c.c: Fix unused variable warning
X-Git-Tag: v2017.03-rc1~139
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c8ac6449797951414cec471e759e7bb0c46f490f;hp=5b30997fd26f0e13837e9ba3cd289a037b8353bd;p=platform%2Fkernel%2Fu-boot.git

power_i2c.c: Fix unused variable warning

The variable ret was added but never set as we did not make calls to
other functions that we needed to check the return value on.

Fixes: 505cf4750ae5 ("power: change from meaningless value to error number")
