Commit 4dc8563363 ("package/alsa-utils:
bump version to 1.2.7") has bumped alsa-utils to 1.2.7, triggering
several build failures in the autobuilders.
The two build issues are fixed by two different patches, both of which
have been submitted upstream.
The first patch fixes:
http://autobuild.buildroot.net/results/c185ad120eb95cb3af0cd3be5fe47c924c565d3e/
The second patch fixes:

Subject: [PATCH] alsactl/info.c: fix conditionals on __ALSA_PCM_H and
|
|
__ALSA_RAWMIDI_H
|
|
|
|
Commit bbc74a61ac7c35e506c3d7f76ecf943cb55736a6 ("alsactl: implement
|
|
'info' command") implemented an alsactl info command. In this
|
|
implementation, there was an attempt to properly address optional
|
|
features from alsa-lib by using conditions on __ALSA_PCM_H,
|
|
__ALSA_RAWMIDI_H.
|
|
|
|
Unfortunately, this attempt does not work entirely: only the code
|
|
inside pcm_device_list(), rawmidi_device_list() was conditionally
|
|
compiled, but their very prototype also use type definitions provided
|
|
in pcm.h and rawmidi.h. So really, it's the entire function that needs
|
|
to be conditionally implemented.
|
|
|
|
Also, snd_rawmidi_stream_name() was not handled properly, for the same
|
|
reason.
|
|
|
|
This commit implements pcm_device_list() only if __ALSA_PCM_H is
|
|
defined, and implements snd_rawmidi_stream_name() and
|
|
rawmidi_device_list() only if __ALSA_RAWMIDI_H is defined.
|
|
|
|
general_card_info() is modified to not call the PCM or raw MIDI
|
|
functions when support is not available.
