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.
