Lothar Waßmann 937222c4dd pwm-backlight: Fix bogus request for GPIO#0 when instantiated from DT ... commit 257462dbf3 ("pwm-backlight: switch to gpiod interface") introduced a regression leading to acquiring a bogus GPIO-0 when configured from DT without an 'enable-gpios' property. The driver will happily accept the 0 initialized 'enable_gpio' member of the struct platform_pwm_backlight_data as valid gpio number, and request this GPIO as enable pin. In case of multiple driver instances, the second will fail to register with the error message: pwm-backlight backlight1.23: failed to request GPIO#0: -16 Fix this by setting enable_gpio in the pdata struct to -EINVAL.
