From 84049e2db59ad9b09461b6d7ec56bd3e8fe75eca Mon Sep 17 00:00:00 2001 From: Cezary Rojewski Date: Fri, 19 Apr 2024 10:48:57 +0200 Subject: ASoC: Intel: avs: Remove unused IRQ-related code Most IRQ-related code is duplicated in the driver. Switch to the new implementation and remove unused members. While the change is non-trivial, from functional perspective status quo is achieved.
