    Subject[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()
    Date
    From: Christophe JAILLET <christophe.jaillet@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")
