Subject: Input: zforce - fix error return code in zforce_start()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3c4396b434613f653bf95f741a6000e671d1e011;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Input: zforce - fix error return code in zforce_start()

The error code was not set if unable to set config, so the error
condition wasn't reflected in the return value. Fix to return a
negative error code from the error handling case instead of 0.
