From 364d2db2791aa3a808d2590ef62c53b4a83c25dd Mon Sep 17 00:00:00 2001 From: Devin Heitmueller Date: Mon, 6 Aug 2012 22:46:54 -0300 Subject: [media] au0828: Make the s_reg and g_reg advanced debug calls work against the bridge The g_reg and s_reg calls worked properly if acting on subdev registers (such as the au8522), but didn't work against the au0828 itself. Copy the logic over from em28xx.
