[alsa-devel] [alsa-lib][PATCH v2 1/3] timer: obsolete legacy rtctimer instance

[Takashi Sakamoto]

At v4.7 development, ALSA timer interface dropped device instance based on
legacy rtctimer implementation. User space applications should not use the
device instance.

This commit adds comments to notify a corresponding macro should not be
used anymore.
