When CONFIG_SND_DYNAMIC_MINORS isn't set, there are only limited
number of devices available, and HD-audio, especially with HDMI/DP
codec, will fail to create more than two devices.
The driver warns about the lack of such devices and skips the PCM
device creations, but the HDMI driver still tries to create the
corresponding JACK, SPDIF and ELD controls even for the non-existing
PCM substreams. This results in confusion on user-space, and even may
break the operation.
Similarly, Intel HDMI/DP codec builds the ELD notification from i915
graphics driver, and this may be broken if a notification is sent for
the non-existing PCM stream.
This patch adds the check of the existence of the assigned PCM
substream in the both scenarios above, and skips the further operation
if the PCM substream is not assigned.

As Smatch recently suggested, a few places in OSS sequencer codes may
expand the array directly from the user-space value with speculation,
namely there are a significant amount of references to either
info->ch[] or dp->synths[] array:
sound/core/seq/oss/seq_oss_event.c:315 note_on_event() warn: potential spectre issue 'info->ch' (local cap)
sound/core/seq/oss/seq_oss_event.c:362 note_off_event() warn: potential spectre issue 'info->ch' (local cap)
sound/core/seq/oss/seq_oss_synth.c:470 snd_seq_oss_synth_load_patch() warn: potential spectre issue 'dp->synths' (local cap)
sound/core/seq/oss/seq_oss_event.c:293 note_on_event() warn: potential spectre issue 'dp->synths'
sound/core/seq/oss/seq_oss_event.c:353 note_off_event() warn: potential spectre issue 'dp->synths'
sound/core/seq/oss/seq_oss_synth.c:506 snd_seq_oss_synth_sysex() warn: potential spectre issue 'dp->synths'
sound/core/seq/oss/seq_oss_synth.c:580 snd_seq_oss_synth_ioctl() warn: potential spectre issue 'dp->synths'
Although all these seem doing only the first load without further
reference, we may want to stay in a safer side, so hardening with
array_index_nospec() would still make sense.
We may put array_index_nospec() at each place, but here we take a
different approach:
- For dp->synths[], change the helpers to retrieve seq_oss_synthinfo
pointer directly instead of the array expansion at each place
- For info->ch[], harden in a normal way, as there are only a couple
of places
As a result, the existing helper, snd_seq_oss_synth_is_valid() is
replaced with snd_seq_oss_synth_info(). Also, we cover MIDI device
where a similar array expansion is done, too, although it wasn't
reported by Smatch.

When get_synthdev() is called for a MIDI device, it returns the fixed
midi_synth_dev without the use refcounting. OTOH, the caller is
supposed to unreference unconditionally after the usage, so this would
lead to unbalanced refcount.
This patch corrects the behavior and keep up the refcount balance also
for the MIDI synth device.

In early stage of firmware SDK, DICE seems to lose its backward
compatibility due to some registers on global address section. I found
this with Alesis Multimix 12 FireWire with ancient firmware (approx.
shipped version).
According to retrieved log from the unit, global section has 96 byte
space. On the other hand, current version of ALSA dice driver assumes
that all of supported unit has at least 100 byte space.
$ ./firewire-request /dev/fw1 read 0xffffe0000000 28
result: 000: 00 00 00 0a 00 00 00 18 00 00 00 22 00 00 00 8a
result: 010: 00 00 00 ac 00 00 01 12 00 00 00 00 00 00 00 00
result: 020: 00 00 00 00 00 00 00 00
This commit adds support for the ancient firmware. Check of global section
is loosened to accept the smaller space. The lack of information is
already compensated by hard-coded parameters.
I experienced that the latest version of Windows driver for this model
can't handle this unit, too. This means that TCAT releases firmware SDK
without backward compatibility for the ancient firmware.
Below list is a early history of driver/firmware package released by
Alesis. I investigated on wayback machine on Internet Archive:
* Unknown: PAL v1.0.41.2, firmware v1.0.3
* Mar 2006: PAL v1.54.0, firmware v1.0.4
* Dec 2006: PAL v2.0.0.2, firmware v2.0
* Jun 2007: PAL v3.0.41.5, firmware v2.0
* Jul 2007: PAL v3.0.56.2. firmware v2.0
* Jan 2008: PAL v3.0.81.1080, firmware v2.0
If I can assume that firmware version is the same as DICE version, DICE
version for the issued firmware may be v1.0.3. According to code base of
userspace driver project (FFADO), I can read DICE v1.0.4 supports global
space larger than 100 byte. I guess the smaller space of global section is
a feature of DICE v1.0.3.

As a side effect, with this change, the radio-miropcm20

It should be noticed that ISAPNP currently depends on ISA.

Krzysztof Kozlowski reported a NULL dereference in _instantiate_card()
on Odroid XU3 and XU boards which he bisected to 45f8cb57da0d7 (ASoC:
core: Allow topology to override machine driver FE DAI link config).
Revert that commit for now, along with f11a5c27f928 (ASoC: core: Add
name prefix for machines with topology rewrites) due to dependency
issues, in order to keep things booting cleanly in -next.
