From: Jiri Slaby Date: Mon, 2 Apr 2012 11:54:00 +0000 (+0200) Subject: TTY: isdn, use tty_port_close_end helper X-Git-Tag: upstream/snapshot3+hdmi~7440^2~30^2~70 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4330d663fed02ace2feba1ab3795ab0c08148a28;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git TTY: isdn, use tty_port_close_end helper The code does almost the same, so there we can leverage the helper's code. The only difference is locking. The helper protects counts by a spinlock. This never hurts and should be added to other code parts too.
