Subject: [media] V4L: fix a confusing function name
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5eba1726e17926d325d7f4efb1593d582bda4dcc;p=openwrt%2Fstaging%2Fblogic.git

[media] V4L: fix a confusing function name

is_state_active_or_queued() actually returns true if the buffer's state
is neither active nore queued. Rename it for clarity.
