[PATCH] pinctrl: nomadik: fix incorrect type in return expression
From: Masahiro Yamada
Date: Fri Aug 04 2017 - 00:51:21 EST
Sparse reports "warning: incorrect type in return expression (different
address spaces)" because nmk_gpio_populate_chip() is supposed to return
(struct nmk_gpio_chip *) whereas devm_ioremap_resource() returns
(void __iomem *). ERR_CAST() is needed to fix the warning.
