From 914a7d429da52b9547064c3b1a2fd4dcf1023b69 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 28 Oct 2019 09:10:56 +0100 Subject: Revert "ALSA: hda: Flush interrupts on disabling" [ Upstream commit 1a7f60b9df614bb36d14dc0c0bc898a31b2b506f ] This reverts commit caa8422d01e983782548648e125fd617cadcec3f. It turned out that this commit caused a regression at shutdown / reboot, as the synchronize_irq() calls seems blocking the whole shutdown. Also another part of the change about shuffling the call order looks suspicious; the azx_stop_chip() call disables the CORB / RIRB while the others may still need the CORB/RIRB update. Since the original commit itself was a cargo-fix, let's revert the whole patch.
