Subject: Char: nozomi, fix tty->count counting
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ee78bb95b7bea08b7774a02073ea2bb45611a9e1;p=linux-beck.git

Char: nozomi, fix tty->count counting

Currently ntty_install omits to increment tty count and we get the
following warnings:
Warning: dev (noz2) tty->count(0) != #fd's(1) in tty_open

So to fix that, add one tty->count++ there.
