ALSA: memalloc: Correctly name as WC
SNDRV_DMA_TYPE_DEV_UC and SNDRV_DMA_TYPE_DEV_UC_SG are incorrectly named as if they were for the uncached memory, while actually we set the pages as write-combined. Rename them to reflect the right attribute. Acked-by: Mark Brown <broonie@kernel.org> Link: https://lore.kernel.org/r/20210802072815.13551-3-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
