From 77430f0396aff1f00ccdda378a661cbfebd5b854 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 3 Jul 2016 07:33:33 -0300 Subject: [PATCH] [media] omap_vout: use control framework Replace the old control code with the control framework. This is one of the few remaining drivers that was not using this framework.
