Subject: [PATCH 4.18 113/158] pinctrl: imx: off by one in imx_pinconf_group_dbg_show()

4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

[ 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")
