Subject: atmel_serial: show tty name in /proc/interrupts
X-Git-Tag: v2.6.25-rc1~110
X-Git-Url: http://www.pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=ae161068756c203ccbeeb9178f4d4f6665d294cf;p=linux-2.6-omap-h63xx.git

atmel_serial: show tty name in /proc/interrupts

When possible, pass the tty name to request_irq() so that the user can easily
distinguish the different serial ports in /proc/interrupts.
