Subject: [PATCH v16 07/10] drm/panel: Use backlight_enable/disable helpers
Date: Tue, 16 Jan 2018 10:35:15 +0000 [thread overview]
Message-ID: <7ade4e0607f04902d6a9cacbe89fea1e99665205.1516098341.git.meghana.madhyastha@gmail.com> (raw)
In-Reply-To: <cover.1516098341.git.meghana.madhyastha@gmail.com>
Use backlight_enable/disable helpers instead of changing
the property and calling backlight_update_status for cleaner
and simpler code and also to avoid repetitions.
