Subject: [PATCH] ALSA: atiixp: Support PCM sync_stop
Git-commit: 4504487d928d5801e8cc52f70e77392cc94d45f5
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518

The driver invokes snd_pcm_period_elapsed() simply from the interrupt
handler.  Set card->sync_irq for enabling the missing sync_stop PCM
operation, as well as removing the superfluous synchronize_irq()
call.
