Subject: drivers/video/backlight/apple_bl.c: include header for exported symbol prototypes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1615d210dbc9c67c38b66bcff53233452dbaae22;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drivers/video/backlight/apple_bl.c: include header for exported symbol prototypes

Include the header to pickup the exported symbol prototype.

Quiets the sparse warning:

  warning: symbol 'apple_bl_register' was not declared. Should it be static?
  warning: symbol 'apple_bl_unregister' was not declared. Should it be static?
