Subject: umbim: call umbim disconnect in error case
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=049870a7fe92834b2438c65200d12f938d219cef;p=openwrt%2Fstaging%2Fmans0n.git

umbim: call umbim disconnect in error case

This is needed to properly close the control channel.

Otherwise, on the next try the caps call may fail.
