commit eb9d84b0ffe39893cb23b0b6712bbe3637fa25fa upstream.

ALSA fireworks driver has a bug in its initial state to return count
shorter than expected by 4 bytes to userspace applications when handling
response frame for Echo Audio Fireworks transaction. It's due to missing
addition of the size for the type of event in ALSA firewire stack.

[ Upstream commit bf0cd60b7e33cf221fbe1114e4acb2c828b0af0d ]

AV/C deferred transaction was supported at a commit 00a7bb81c20f ("ALSA:
firewire-lib: Add support for deferred transaction") while 'deferrable'
flag can be uninitialized for non-control/notify AV/C transactions.
UBSAN reports it:

This commit fixes the bug. The bug has no disadvantage for the non-
control/notify AV/C transactions since the flag has an effect for AV/C
response with INTERIM (0x0f) status which is not used for the transactions
in AV/C general specification.

[ Upstream commit 50ebe56222bfa0911a932930f9229ee5995508d9 ]

A user of FFADO project reported the issue of ToneWeal FW66. As a result,
the device is identified as one of applications of BeBoB solution.

I note that in the report the device returns contradictory result in plug
discovery process for audio subunit. Fortunately ALSA BeBoB driver doesn't
perform it thus it's likely to handle the device without issues.

I receive no reaction to test request for this patch yet, however it would
be worth to add support for it.

[ Upstream commit 5d6fb80a142b5994355ce675c517baba6089d199 ]

This reverts commit 0edabdfe89581669609eaac5f6a8d0ae6fe95e7f.

I've explained that optional FireWire card for d.2 is also built-in to
d.2 Pro, however it's wrong. The optional card uses DM1000 ASIC and has
'Mackie DJ Mixer' in its model name of configuration ROM. On the other
hand, built-in FireWire card for d.2 Pro and d.4 Pro uses OXFW971 ASIC
and has 'd.Pro' in its model name according to manuals and user
experiences. The former card is not the card for d.2 Pro. They are similar
in appearance but different internally.

commit 0edabdfe89581669609eaac5f6a8d0ae6fe95e7f upstream.

Mackie d.2 has an extension card for IEEE 1394 communication, which uses
BridgeCo DM1000 ASIC. On the other hand, Mackie d.4 Pro has built-in
function for IEEE 1394 communication by Oxford Semiconductor OXFW971,
according to schematic diagram available in Mackie website. Although I
misunderstood that Mackie d.2 Pro would be also a model with OXFW971,
it's wrong. Mackie d.2 Pro is a model which includes the extension card
as factory settings.

This commit fixes entries in Kconfig and comment in ALSA OXFW driver.

As snd_ff.rx_bytes[] is unsigned int, and NSEC_PER_SEC is 1000000000L,
the second multiplication in

    ff-&gt;rx_bytes[port] * 8 * NSEC_PER_SEC / 31250

always overflows on 32-bit platforms, truncating the result.  Fix this
by precalculating "NSEC_PER_SEC / 31250", which is an integer constant.

Note that this assumes ff-&gt;rx_bytes[port] &lt;= 16777.

Tascam FE-8 is known to support communication by asynchronous transaction
only. The support can be implemented in userspace application and
snd-firewire-ctl-services project has the support. However, ALSA
firewire-tascam driver is bound to the model.

This commit changes device entries so that the model is excluded. In a
commit 53b3ffee7885 ("ALSA: firewire-tascam: change device probing
processing"), I addressed to the concern that version field in
configuration differs depending on installed firmware. However, as long
as I checked, the version number is fixed. It's safe to return version
number back to modalias.

commit acd46a6b6de88569654567810acad2b0a0a25cea upstream.

Avid Adrenaline is reported that ALSA firewire-digi00x driver is bound to.
However, as long as he investigated, the design of this model is hardly
similar to the one of Digi 00x family. It's better to exclude the model
from modalias of ALSA firewire-digi00x driver.

This commit changes device entries so that the model is excluded.
