Subject: [alsa-devel] [PATCH for-5.6 4/4] ALSA: ctl: bump protocol version up to v2.1.0
Date: Mon, 23 Dec 2019 11:39:21 +0900
Message-ID: <> (raw)
In-Reply-To: <>

In a development period for v5.6 kernel, some changes are introduced to
structures in ALSA control interface:
 - 'tstamp' member is removed from 'struct snd_ctl_elem_value
 - 'TSTAMP' flag is removed from a set of access flags for 'struct
 - 'dimen' member is removed from 'struct snd_ctl_elem_info

Although these changes were introduced with enough consideration for
backward compatibility, they include slightly lose of it. This commit
bumps protocol version of ALSA control interface up to v2.1.0.
