[PATCH AUTOSEL 4.18 076/131] pinctrl: imx: off by one in imx_pinconf_group_dbg_show()

From: Sasha Levin
Date: Sun Sep 02 2018 - 09:32:53 EST


From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit b4859f3edb47825f62d1b2efdd75fe7945996f49 ]

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")
