From adb65bc71c8fef53822870cc9018f05b11131233 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 25 Jun 2008 06:32:44 -0300 Subject: V4L/DVB (8113): ivtv/cx18: remove s/g_ctrl, now all controls are handled through s/g_ext_ctrl videodev converts old-style controls to an extended control so the ivtv and cx18 drivers no longer have to handle both.
