Subject: backlight: tps65217_bl: Remove unnecessary default brightness check
X-Git-Tag: v4.15-rc1~86^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5158cc2d4eca66c1c5ef1939d8fa02942f532515;p=thirdparty%2Fkernel%2Flinux.git

backlight: tps65217_bl: Remove unnecessary default brightness check

Variable val holds the default brightness and is unsigned, therefore
checking whether it is less than zero is redundant.
