Subject: Input: lm8323 - missing error check in lm8323_set_disable()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3b5005e9206af245033e9209eee193f3d7b2f636;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Input: lm8323 - missing error check in lm8323_set_disable()

The missing error handling here is not especially harmful but static
checkers complain that "i" can be used uninitialized.
