Subject: TTY: amiserial/simserial, use close delays from tty_port
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=799be6ff2fd7294f428a9e68a7786490c862c1af;p=mv-sheeva.git

TTY: amiserial/simserial, use close delays from tty_port

Note that previously simserial set the delay to 0. So we preserve
that. BUT, is it correct?
