Subject: media: omap3isp: Fix check for our own sub-devices
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=eae4cf8f262e35b60928058e36ce1e841a2ab917;p=openwrt%2Fstaging%2Fblogic.git

media: omap3isp: Fix check for our own sub-devices

We only want to link sub-devices that were bound to the async notifier the
isp driver registered but there may be other sub-devices in the
v4l2_device as well. Check for the correct async notifier.
