Subject: powerpc: ppc4xx: drop unused variable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ab503238ff6974b9a51d328c2a55c505064c64f7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

powerpc: ppc4xx: drop unused variable

commit 0d36fe65f58391712e11a6621075f373216e5f00
"powerpc: ppc4xx: use gpiochip data pointer"
made the mm_gc local variable in ppc4xx_gpio_set()
redundant, and when GCC treats warnings as errors this
happens:

arch/powerpc/sysdev/ppc4xx_gpio.c: In function 'ppc4xx_gpio_set':
arch/powerpc/sysdev/ppc4xx_gpio.c:93:26: error:
  unused variable 'mm_gc' [-Werror=unused-variable]
     struct of_mm_gpio_chip *mm_gc = to_of_mm_gpio_chip(gc);
                             ^
   cc1: all warnings being treated as errors
