ALSA: Add ifdef CONFIG_GENERIC_ALLOCATOR for SNDRV_DMA_TYPE_IRAM code
It turned out that we can't use gen_pool_*() functions on archs without CONFIG_GENERIC_ALLOCATOR (resulting in missing symbols), since linux/genalloc.h doesn't provide dummy functions for all. We'd be able to fix linux/genalloc.h size, but I take an easier path for now... Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
