Subject: tty: Power: fix suspend vt regression
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=797938b5e33991dadf4dd9228b932cc69c3e905a;p=openwrt%2Fstaging%2Fblogic.git

tty: Power: fix suspend vt regression

vt_waitactive no longer accepts console parameter as console-1
since commit "vt: add an event interface". It expects console
number directly (as viewed by userspace -- counting from 1).

Fix a deadlock suspend regression by redefining adding one
to vt in vt_move_to_console.
