From e4bc6272ab3f7cb0b56705f78320e361880411e1 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 21 Sep 2011 07:54:44 -0300 Subject: [PATCH] [media] omap3isp: preview: Remove horizontal averager support The horizontal averager isn't used and will get in the way when implementing cropping support on the input pad. Remove it, it can be added back later if needed.
