X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=320da0d23ed1f82a896e0cfc1549a896d267777a;p=openwrt%2Fstaging%2Fblogic.git [PATCH] hvc_console: Unregister the console in the exit routine. Be thorough in our exit routine, since it says it is there to be so. Unregistering without registering is safe (checked in 2.6.10).
