Subject: [PATCH] Change dash2underscore() return value to char
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b9e20a920092eb3840424f85c78852c0433df00d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] Change dash2underscore() return value to char

Since dash2underscore() just operates and returns chars, I guess its safe
to change the return value to a char.  With my .config, this reduces its
size by 5 bytes.

   4150     152       0    4302    10ce params.o
