Subject: [PATCH] pinctrl: imx: off by one in imx_pinconf_group_dbg_show()
Date: Thu, 19 Jul 2018 08:16:48 +0000	[thread overview]
Message-ID: <20180719081648.o6ug4z3t42mrsmop@mwanda> (raw)

The > should really be >= here.  It's harmless because
pinctrl_generic_get_group() will return a NULL if group is invalid.

Fixes: ae75ff814538 ("pinctrl: pinctrl-imx: add imx pinctrl core driver")
Reported-by: Dong Aisheng <aisheng.dong@nxp.com>
