Subject: [PATCH] ALSA: ca0106: Support PCM sync_stop
Git-commit: 339ede502a00af9c32ce1b585a6be94f2d4f96c9
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.
