Subject: [PATCH v2] backlight: Convert from Legacy pm ops to dev_pm_ops
Date: Wed, 14 Nov 2040 04:27:17 -0700 [thread overview]
Message-ID: <2236505237-3336-1-git-send-email-shuah.kh@samsung.com> (raw)
Convert drivers/video/backlight/class to use dev_pm_ops for power
management and remove Legacy PM ops hooks. With this change, rtc class
registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of
Legacy class->suspend/resume. When __device_suspend() runs call-backs,
it will find class->pm ops for the backlight class.
