[PATCH] gpio: generic: make bgpio_pdata always visible

From: Arnd Bergmann
Date: Sat Jan 09 2016 - 16:17:22 EST


Board files that define their own bgpio_pdata are broken when
CONFIG_GPIO_GENERIC is disabled and the bgpio_pdata structure
definition is hidden by the #ifdef:

arch/arm/mach-clps711x/board-autcpu12.c:148:15: error: variable 'autcpu12_mmgpio_pdata' has initializer but incomplete type
static struct bgpio_pdata autcpu12_mmgpio_pdata __initdata = {
arch/arm/mach-clps711x/board-autcpu12.c:149:2: error: unknown field 'base' specified in initializer
.base = AUTCPU12_MMGPIO_BASE,

Since the board files should generally not care what drivers are
enabled, this makes the structure definition visible again.
