Subject: [media] pwc: failure to submit an urb is a fatal error
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=622d9f5d302e99dc7a06cb442e9d9ff2bb0f59b5;p=openwrt%2Fstaging%2Fblogic.git

[media] pwc: failure to submit an urb is a fatal error

Failure to submit an urb is a fatal error, make isoc_init return an
error when this happens rather then only log it.
