6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ying Liu <victor.liu@xxxxxxx>
[ Upstream commit fe1328b5b2a087221e31da77e617f4c2b70f3b7f ]
So, let's drop output GPIO direction check and only check GPIO value to set
the initial power state.
Fixes: 706dc68102bc ("backlight: gpio: Explicitly set the direction of the GPIO")
