-Subject: platform/loongarch: laptop: Add backlight power control support
-
-From: Yao Zi <ziyao@disroot.org>
-
-commit 53c762b47f726e4079a1f06f684bce2fc0d56fba upstream.
-
-loongson_laptop_turn_{on,off}_backlight() are designed for controlling
-the power of the backlight, but they aren't really used in the driver
-previously.
-
-Unify these two functions since they only differ in arguments passed to
-ACPI method, and wire up loongson_laptop_backlight_update() to update
-the power state of the backlight as well. Tested on the TongFang L860-T2
-Loongson-3A5000 laptop.
-
-Cc: stable@vger.kernel.org
-Fixes: 6246ed09111f ("LoongArch: Add ACPI-based generic laptop driver")
