Subject: [PATCH v16 08/10] drm/omapdrm: Use backlight_enable/disable helpers
Date: Tue, 16 Jan 2018 10:35:57 +0000	[thread overview]
Message-ID: <59f488eaddc4ec0896851ede1ade5062fb2ad3be.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.
