Subject: media: v4l: async: Don't set sd->dev NULL in v4l2_async_cleanup
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=99b7a995a4a02522292ea6313bd626a33fb0e037;p=openwrt%2Fstaging%2Fblogic.git

media: v4l: async: Don't set sd->dev NULL in v4l2_async_cleanup

v4l2_async_cleanup() is called when the async sub-device is unbound from
the media device. As the pointer is set by the driver registering the
async sub-device, leave the pointer as set by the driver.
