From: Shuah Khan Date: Fri, 19 Feb 2016 00:28:48 +0000 (-0200) Subject: [media] media: au0828 enable the right media source when input changes X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=050b6c98b42ff77894da2aad34fcf0d4e1fed8e7;p=openwrt%2Fstaging%2Fblogic.git [media] media: au0828 enable the right media source when input changes Change vidioc_s_input() to enable the media source for the newly selected input. v4l2-core enables source before calling au0828's vidioc_s_input() handler. Hence, when input selection changes, media source for the newly selected input needs to be enabled.
