Subject: [media] hdpvr: fix querystd 'unknown format' return
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ab6e134a48a58b111f28dfb5c8440a56d6be10c5;p=openwrt%2Fstaging%2Fblogic.git

[media] hdpvr: fix querystd 'unknown format' return

If no format has been detected, then querystd should return V4L2_STD_UNKNOWN,
not V4L2_STD_ALL.
