ALSA: au88xx: Add fall-through annotations
As a preparatory patch for the upcoming -Wimplicit-fallthrough compiler checks, add the "fall through" annotation in au88xx driver. Although the usages in both both functions vortex_adbdma_setbuffers() and vortex_wtdma_setbuffers() look a bit suspicious, we keep the behavior as before, just to be safer. If it were broken, we should have already received bug reports. Signed-off-by: Takashi Iwai <tiwai@suse.de>
