From cac99f73f0752e1c83674e12fb2c605dca9ce474 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Thu, 31 Oct 2024 20:32:52 +0100 Subject: [PATCH] ALSA: hda: intel: Don't free interrupt when suspending There's no need to free/re-request the interrupt on system suspend. PCI core takes care, using functions like pci_restore_msi_state().
