    Subject[PATCH 08/13] video/backlight: LM3630A needs PWM
    Date
    The LM3630A driver cannot be successfully built if we don't
    enable the PWM subsystem. This patch makes that dependency
    explicit in Kconfig and prevents broken randconfig builds.

    Based on Arnd Bergmann patch but split out into seperate
    commits per driver based on feedback.
