Subject: [PATCH v2 21/21] drm/omap: Don't call HDMI mode and infoframe operations recursively
Date: Mon,  6 Aug 2018 23:23:15 +0300	[thread overview]
Message-ID: <20180806202315.6329-22-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20180806202315.6329-1-laurent.pinchart@ideasonboard.com>

The HDMI mode (.set_hdmi_mode()) and infoframe (.set_infoframe())
operations are called recursively from the display device back to the
HDMI encoder. This isn't required, as all components other than the HDMI
encoder just forward the operation to the previous component in the
chain. Call the operations directly on the HDMI encoder.
