The error for a -ve value in ret is redundant as all previous assignments to ret have an associated -ve check and hence it is impossible for ret to be less that zero at the point of the check.

At present, all of models produced by TC Electronic except for Konnekt Live are supported with hard-coded their stream formats. Studio Konnekt 48 is sore model to support dual streams for both directions. The second stream has no MIDI conformant data channel in its data block. But current implementation transfers the second stream with MIDI conformant data channel. This commit fixes this issue. Signed-off-by:

Takashi Sakamoto authored
TC Electronic Studio Konnekt 48 is an application of combination of WaveFront Dice II STD and TC Applied Technologies (TCAT) TCD2210 (Dice Mini). The latter is on a board with BNC and optical interfaces, thus used for signal processing for word clock, S/PDIF and ADAT. This model doesn't support TCAT extended application protocol. For such devices, ALSA dice driver needs to have hard-coded parameters for stream formats. This commit fixes stream format parameters for this model. Unfortunately, at sampling transmission frequencies over 48.0kHz, I confirmed that current ALSA dice driver doesn't drive the device appropriately to generate sounds (silence). I guess that this comes from timestamping quirk of Dice-based devices, which I reported.

TC Electronic Digital Konnekt x32 is an application of WaveFront DiceII STD and doesn't support TCAT extended application protocol. For such devices, ALSA dice driver needs to have hard-coded parameters for stream formats. This commit adds stream format parameters for this model.

There are still many places calling the timer's hw.c_resolution callback without lock, and this may lead to some races, as we faced in the commit a820ccbe ("ALSA: pcm: Fix UAF at PCM release via PCM timer access"). This patch changes snd_timer_resolution() to take the timer->lock for avoiding the races. A place calling this function already inside the lock (from the notifier) is replaced with the snd_timer_hw_resolution() accordingly, as well as wrapping with the lock around another place calling snd_timer_hw_resolution(), too.

Takashi Iwai authored
The commit 289ca025 ("ALSA: Use priority list for managing device list") changed the way to register/disconnect/free devices via a single priority list. This helped to make behavior consistent, but it also changed a slight behavior change: namely, the control device is registered earlier than others, while it was supposed to be the very last one. I've put SNDRV_DEV_CONTROL in the current position as the release of ctl elements often conflict with the private ctl elements some PCM or other components may create, which often leads to a double-free. But, the order of register and disconnect should be indeed fixed as expected in the early days: the control device gets registered at last, and disconnected at first. This patch changes the priority list order to move SNDRV_DEV_CONTROL as the last guy to assure the register / disconnect order. Meanwhile, for keeping the messy resource release order, manually treat the control and lowlevel devices as last freed one. Additional note: The lowlevel device is the device where a card driver creates at probe. And, we still keep the release order control -> lowlevel, as there might be link from a control element back to a lowlevel object.
