From 72c851b00f6c86353c54fdd9f1ef88d82e8df6c5 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 6 Aug 2010 10:53:19 -0300 Subject: [PATCH] V4L/DVB: cx25840/ivtv: replace ugly priv control with s_config The cx25840 used a private control CX25840_CID_ENABLE_PVR150_WORKAROUND to be told whether to enable a workaround for certain pvr150 cards. This is really config data that it needs to get at load time. Implemented this in cx25840 and ivtv.
