ALSA: es1938: Support PCM sync_stop
The driver invokes snd_pcm_period_elapsed() simply from the interrupt handler. Set card->sync_irq for enabling the missing sync_stop PCM operation. It's cleared and reset dynamically at IRQ re-acquiring for the PM resume, too. Link: https://lore.kernel.org/r/20191210063454.31603-19-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
