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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

Update the error handling code accordingly.
