[PATCH 5.7 318/477] pinctrl: freescale: imx: Use devm_of_iomap() to avoid a resource leak in case of error in imx_pinctrl_probe()

[Greg Kroah-Hartman]

From: Christophe JAILLET <christophe.jail...@wanadoo.fr>

[ Upstream commit ba403242615c2c99e27af7984b1650771a2cc2c9 ]

Use 'devm_of_iomap()' instead 'of_iomap()' to avoid a resource leak in
case of error.

Update the error handling code accordingly.

Fixes: 26d8cde5260b ("pinctrl: freescale: imx: add shared input select reg 
support")
