pinctrl: fix "warning: 'struct pinctrl_dev' declared inside parameter list"
when pinctl subsystem is not selected, when compiling drivers including the include/linux/pinctrl/pinctrl.h, we will get the warning as below: In file included from include/linux/pinctrl/pinmux.h:17, from drivers/tty/serial/sirfsoc_uart.c:25: include/linux/pinctrl/pinctrl.h:126: warning: 'struct pinctrl_dev' declared inside parameter list include/linux/pinctrl/pinctrl.h:126: warning: its scope is only this definition or declaration, which is probably not what you want Signed-off-by: Barry Song <Baohua.Song@csr.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
