Subject: power: regulator: max77686 correct variable type
X-Git-Tag: v2015.10-rc2~156
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=8640522d2d2d26caaf1805f3de696a7a6fb1cc22;p=u-boot

power: regulator: max77686 correct variable type

The return type of pmic_read and pmic_write is signed int, so
correct variable 'ret' from type unsigned int to int.
