[PATCH 1/1] pinctrl: pinctrl-mxs: fix a compiling error

[Dong Aisheng]

From: Dong Aisheng <dong.aisheng at linaro.org>

The compiling error is:
drivers/pinctrl/pinctrl-mxs.c: In function 'mxs_dt_node_to_map':
drivers/pinctrl/pinctrl-mxs.c:140: error: implicit declaration of function 'free'
drivers/pinctrl/pinctrl-mxs.c:140: warning: incompatible implicit declaration of built-in function 'free'
It should be kfree.
