X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=57da5e47ccf3d727958aeef7675154d48635fa09;p=openwrt%2Fstaging%2Fblogic.git

[media] v4l: omap4iss: Remove unneeded status variable

The failure variable is initialized with 0 and used as a return value
without ever being modified. Remove it and return 0 directly.
