From a103a3989993859091a26936b9337a8e09330fc3 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 26 Dec 2019 11:03:53 +0100 Subject: ALSA: control: Fix incompatible protocol error The recent change to bump the ALSA control API protocol version from 2.0.7 to 2.1.0 caused a regression on user-space; while the user-space expects both the major and the minor versions to be identical with the supported numbers, we changed the minor number from 0 to 1. For recovering from the incompatibility, this patch changes the protocol version again to 2.0.8, which is compatible, but yet higher than the original number 2.0.7, indicating that the protocol change.
