Subject: [media] em28xx-v4l: do not call em28xx_init_camera() if the device has no sensor
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d86bc65a64e1e1536d9f5f3287f8707997b4e8fc;p=openwrt%2Fstaging%2Fblogic.git

[media] em28xx-v4l: do not call em28xx_init_camera() if the device has no sensor

This avoids the unnecessary temporary registration of a dummy V4L2 clock.
