H A Dgpio.h4e4438b8 Wed Sep 01 09:55:24 CDT 2010 Anton Vorontsov <cbouatmailru@gmail.com> gpiolib: Add 'struct gpio_chip' forward declaration for !GPIOLIB case

With CONFIG_GPIOLIB=n, the 'struct gpio_chip' is not declared,
so the following pops up on PowerPC:

cc1: warnings being treated as errors
In file included from arch/powerpc/platforms/52xx/mpc52xx_common.c:19:
include/linux/of_gpio.h:74: warning: 'struct gpio_chip' declared
inside parameter list
include/linux/of_gpio.h:74: warning: its scope is only this definition
or declaration, which is probably not what
you want
include/linux/of_gpio.h:75: warning: 'struct gpio_chip' declared
inside parameter list
make[2]: *** [arch/powerpc/platforms/52xx/mpc52xx_common.o] Error 1

This patch fixes the issue by providing the proper forward declaration.
