MIPS non-coherent archs need the noncached pgprot in mmap of PCM buffers. But, since the coherency needs to be checked dynamically via plat_device_is_coherent(), we need an ugly check dependent on MIPS in ALSA core code. This should be cleaned up in MIPS arch side (e.g. creating dma_mmap_coherent()) in near future. Tested-by: Wu Zhangjin <wuzhangjin@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
