In case when dB information does not appear as the only TLV type in the

This commit fixes it by distinguishing between TLV parse error and dB

spcm->info bits should be a copy of the slave PCM info as is.

Fixes: 982786e9ebff ("Fix bogus pause flag on dmix") Signed-off-by: Takashi Iwai <tiwai@suse.de>
The fix for PCM dmix suspend/resume checks spcm->info bit of
SND_PCM_INFO_RESUME for applying a workaround for drivers with the
full resume support. This assumed that scpm->info is exposed from the
underlying slave PCM device.
The above is true for the first opened instance, but for the second
opened instance, it's a copy from the saved data in shmem. And, we
dropped SND_PCM_INFO_RESUME bit there to assure not to expose the full
resume capability to applications. This resulted in the
inconsistencies, and when the second instance is resumed at first, it
misses the snd_pcm_resume() call, hence the driver doesn't react
properly any longer.
For addressing it, we keep SND_PCM_INFO_RESUME bit in shmptr->s.info
bits as is, while dropping the bit exposed to apps in
snd_pcm_direct_hw_refine() and *_hw_params() callbacks.

A UMP MIDI 2.0 device allow to have an optional MIDI 1.0 port while
speaking in MIDI 2.0 protocol for other UMP Groups. The new seq port

This is rather a minor difference, and since ALSA sequencer core
covers the all conversions, usually you don't have to worry about it
at all.

snd_seq_create_ump_block() receives a snd_ump_block_info_t data at the

means the connectivity, but the current code translated other way
round. The correct translation should be that input = receiver, i.e.
a writable port for applications, and output = source, a readable port
for applications.
