ALSA: pci: Simplify with dma_set_mask_and_coherent()
Many PCI drivers still have two explicit calls of dma_set_mask() and dma_set_coherent_mask(). Let's simplify with dma_set_mask_and_coherent(). Link: https://lore.kernel.org/r/20210114125412.993-2-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
