Compilation failure in gpio-vf610.c

[Tariq Toukan <ttoukan.linux@gmail.com>]

Hi,

Recently we started seeing the compilation error:

drivers/gpio/gpio-vf610.c: In function ‘vf610_gpio_direction_input’:
drivers/gpio/gpio-vf610.c:120:9: error: implicit declaration of function 
‘pinctrl_gpio_direction_input’; did you mean 
‘vf610_gpio_direction_input’? [-Werror=implicit-function-declaration]
   120 |  return pinctrl_gpio_direction_input(chip->base + gpio);
       |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
       |         vf610_gpio_direction_input


Is it a known issue? Is there a fix we can cherry-pick?

Offending patch:

     gpio: vf610: drop the SOC_VF610 dependency for GPIO_VF610

     i.MX7ULP, i.MX8 and i.MX9 use this driver, so drop
     the SOC_VF610 dependcy to make the driver could be built
     for i.MX platform.

This seems to solve the issue.
Is it the proper way for solving this?
