Subject: [PATCH] pinctrl: single: check if #pinctrl-cells exceeds 3
Date: Sun, 13 Sep 2020 23:08:25 +0200	[thread overview]
Message-ID: <20200913210825.2022552-1-drew@beagleboard.org> (raw)

The property #pinctrl-cells can either be 2 or 3.  There is currently
only a check to make sure that #pinctrl-cells is 2 or greater.  This
patch adds a check to make sure it is not greater than 3.

Fixes: a13395418888 ("pinctrl: single: parse #pinctrl-cells = 2")
Reported-by: Trent Piepho <tpiepho@gmail.com>
