Subject: acpi-video-detect: Make acpi_video_get_capabilities a private function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fb105d964226ce4834b45d7e3d9f339aa716ed70;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

acpi-video-detect: Make acpi_video_get_capabilities a private function

acpi_video_get_capabilities() is only used inside video_detect.c so make
it static. While at it also remove the prototype for the non existent
acpi_video_display_switch_support function from acpi.h
