Subject: [PATCH 1/2] drm: adv7511: Fix DDC error interrupt reset
Date: Wed, 18 Feb 2015 15:30:01 +0200	[thread overview]
Message-ID: <1424266202-25339-2-git-send-email-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <1424266202-25339-1-git-send-email-laurent.pinchart+renesas@ideasonboard.com>

The DDC error interrupt bit is located in REG_INT1, not REG_INT0. Update
the interrupt sources reset code accordingly.
