Laxman Dewangan [off-list ref] hat am 24.

The remove callback is implemented as:
int mxs_pinctrl_remove(struct platform_device *pdev)
{
struct mxs_pinctrl_data *d = platform_get_drvdata(pdev);
pinctrl_unregister(d->pctl);
iounmap(d->base);
return 0;
}
So if I use devm_pinctrl_register() then the sequence will be different like
iounmap()
pinctrl_unregister()
And I did not want to change the sequence as dont know the side effect
until I test it on actual platform which is not there with me.
