[PATCH v3 4/4] mfd: cros_ec: Register keyboard backlight subdevice

From: Thomas Weißschuh
Date: Sun May 26 2024 - 14:18:56 EST


Load cros_kbd_led_backlight when the EC reports EC_FEATURE_PWM_KEYB.
This makes cros_kbd_led_backlight work on machines without specific
ACPI or OF support for the keyboard backlight.
