gpiolib uses a fixed string for the suffixes and defines it at 32 bytes. Later in the code snprintf is used with this fixed value of 32. Using sizeof() is safer in case the size for the suffixes is ever changed. Signed-off-by: NOlliver Schinagl <oliver@schinagl.nl> Signed-off-by: NLinus Walleij <linus.walleij@linaro.org>

This reverts commit da788acb. That commit tried to fix the section mismatch warning by moving the ppc_corenet_clk_driver struct to init section. This is definitely wrong because the kernel would free the memories occupied by this struct after boot while this driver is still registered in the driver core. The kernel would panic when accessing this driver struct.
