Subject: ARM: OMAP2+: Fix zoom LCD backlight if TWL_CORE is not selected
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=38232f7bd112bba6dd65309a218f21d3171c84fd;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ARM: OMAP2+: Fix zoom LCD backlight if TWL_CORE is not selected

Otherwise we get:
