3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Lars-Peter Clausen <lars@metafoo.de> commit 59516b07b4ffa7e607a5787674ea3c405f1b390c upstream. The microblaze architecture does not provide a native GPIO API implementation nor requires GPIOLIB, but still selects GENERIC_GPIO by default. As a result the following build error occurs, if GPIOLIB is not selected: include/asm-generic/gpio.h: In function 'gpio_get_value_cansleep': include/asm-generic/gpio.h:218: error: implicit declaration of function '__gpio_get_value' include/asm-generic/gpio.h: In function 'gpio_set_value_cansleep': include/asm-generic/gpio.h:224: error: implicit declaration of function '__gpio_set_value' This patch addresses the issue by not selecting GENERIC_GPIO by default. This causes the GPIO API to be stubbed out if no implementation is provided.
