Subject: [PATCH] serial: mpsc driver passes bad devname to request_irq()
X-Git-Tag: firefly_0821_release~37168
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a30ff2e348af9d3a1782103130c88960550a773f;p=firefly-linux-kernel-4.4.55.git

[PATCH] serial: mpsc driver passes bad devname to request_irq()

The devname passed to request_irq() contained a '/' which is wrong.  At
a minimum, the '/' prevented the devname from showing up in
/proc/irq/<irq>/<devname>.  This patch replaces the '/' with a '-' to
fixes that problem.
