[alsa-devel] [PATCH 1/2] gpio: add GPIOF_ values regardless on kconfig settings

[Randy Dunlap]

From: Randy Dunlap <randy.dunlap at oracle.com>

Make GPIOF_ defined values available even when GPIOLIB nor GENERIC_GPIO
is enabled by moving them to <linux/gpio.h>.

Fixes these build errors in linux-next:
sound/soc/codecs/ak4641.c:524: error: 'GPIOF_OUT_INIT_LOW' undeclared (first use in this function)
sound/soc/codecs/wm8915.c:2921: error: 'GPIOF_OUT_INIT_LOW' undeclared (first use in this function)
