Subject: [PATCH] ALSA: emu10k1: Support PCM sync_stop
Git-commit: 66471aa715f0d4207c61e27e6333d6f453df554b
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.
