From 24d1e49415be546470b20429d748e240d0518b7e Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 8 Jul 2021 11:07:38 +0200 Subject: ALSA: intel8x0: Fix breakage at ac97 clock measurement The recent workaround for the wild interrupts in commit c1f0616124c4 ("ALSA: intel8x0: Don't update period unless prepared") leaded to a regression, causing the interrupt storm during ac97 clock measurement at the driver probe. We need to handle the interrupt while the clock measurement as well as the proper PCM streams.
