From 66d4e49b09fb170c0eb6901e288450eaf29ba6c7 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 16 Apr 2020 12:19:28 +0800 Subject: [PATCH] ALSA: aica: Fix a long-time build breakage [ Upstream commit 534420c6ff87d3052540f1fd346e0adcff440819 ] The build of aica sound driver has been broken since the timer API conversion and some code rewrite. This patch fixes the breakage by using the common substream field, as well as a bit cleaning up wrt the timer handling in the code.
