Subject: [PATCH] backlight: pwm_bl: Don't use GPIOF_* with gpiod_get_direction
Git-commit: bb084c0f61d659f0e6d371b096e0e57998f191d6
Patch-mainline: v4.18-rc1
References: bsc#1051510
The documentation was wrong, gpiod_get_direction() returns 0/1 instead
of the GPIOF_* flags. The docs were fixed with commit 94fc73094abe47
("gpio: correct docs about return value of gpiod_get_direction"). Now,
fix this user (until a better, system-wide solution is in place).
