From ecc2fe20e63a21b7db23065ff061b66fbc08e08b Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 30 Nov 2015 14:47:00 -0200 Subject: [PATCH] [media] cx23885: video instead of vbi register used The VID_A_GPCNT register is for video, not vbi. Read from the right register and don't write to the video register. Based upon Devin's initial patch made for an older kernel which I cleaned up and rebased. Thanks to Kernel Labs for that work.
