Subject: [PATCH] gpio/msm_v1: CONFIG_GPIO_MSM_V1 is only available on three
 SoCs

The feature GPIO_MSM_V1 is only available on three SoCs. On all other MSM SoCs
the INT_GPIO_GROUP{1,2} is undeclared, but Kconfig does allow such
configurations. Therefore the produced configuration is valid, but does not
compile. The problem is fixed by adding the missing Kconfig constraints.

drivers/gpio/gpio-msm-v1.c: In function âmsm_init_gpioâ:
drivers/gpio/gpio-msm-v1.c:629:26: error: 'INT_GPIO_GROUP1' undeclared
drivers/gpio/gpio-msm-v1.c:630:26: error: 'INT_GPIO_GROUP2' undeclared

I added a configuration, which should reproduce the compilation error
directly.
