[PATCH] pinctrl: sh-pfc: Kill unused variable in sh_pfc_remove()

[Geert Uytterhoeven]

If CONFIG_PINCTRL_SH_PFC_GPIO=n:

    drivers/pinctrl/sh-pfc/core.c: In function 'sh_pfc_remove':
    drivers/pinctrl/sh-pfc/core.c:649:17: warning: unused variable 'pfc' [-Wunused-variable]

Fixes: 67ec8d7b48463904 ("pinctrl: ish-pfc: Use devm_pinctrl_register() for pinctrl registration")

---
I won't queue this up in sh-pfc-for-v4.7, as the offending commit is not in
that branch.

Ideally, you dont need the call of sh_pfc_unregister_gpiochip() if you 
use the devm_gpiochip_add_data() which is already available on all 
subsystem.

int sh_pfc_unregister_gpiochip(struct sh_pfc *pfc)
{
         gpiochip_remove(&pfc->gpio->gpio_chip);
#ifdef CONFIG_SUPERH
         gpiochip_remove(&pfc->func->gpio_chip);
#endif
         return 0;
}

So you can get rid of this calls and lines.
