Some ioctl functions are implemented individually for both playback and capture streams although most of the codes are identical with just a few different stream-specific function calls. This patch unifies these places, removes the superfluous trivial check and flattens the call paths as a cleanup. Meanwhile, for better readability, some codes (e.g. xfer ioctls or forward/rewind ioctls) are factored out as functions. Signed-off-by: Takashi Iwai <tiwai@suse.de>

Currently we're taking power_lock at each card component for assuring the power-up sequence, but it doesn't help anything in the implementation at the moment: it just serializes unnecessarily the callers, but it doesn't protect about the power state change itself. It used to have some usefulness in the early days where we managed the PM manually. But now the suspend/resume core procedure is beyond our hands, and power_lock lost its meaning. This patch drops the power_lock from allover the places. There shouldn't be any issues by this change, as it's no helper regarding the power state change. Rather we'll get better performance by removing the serialization; which is the only slight concern of any behavior change, but it can't be a showstopper, after all.

PCM OSS emulation issues the drain ioctl without power lock. It used to work in the earlier kernels as the power lock was taken inside snd_pcm_drain() itself. But since 68b4acd3 ("ALSA: pcm: Apply power lock globally to common ioctls"), the power lock is taken outside the function. Due to that change, the call via OSS emulation leads to the unbalanced power lock, thus it deadlocks. As a quick fix, just take the power lock before snd_pcm_drain() call for OSS emulation path. A better cleanup will follow later.

Not all devices with ACPI and this combination of sound devices will have the required information provided via ACPI. Reintroduce the I2C device ID to restore sound functionality on on the Chromebook 'Samus' model. [ More background note: the commit a36afb0a ("ASoC: rt5677: Introduce proper table...") moved the i2c ID probed via ACPI ("RT5677CE:00") to a proper acpi_device_id table. Although the action itself is correct per se, the overseen issue is the reference id->driver_data at rt5677_i2c_probe() for retrieving the corresponding chip model for the given id. Since id=NULL is passed for ACPI matching case, we get an Oops now. We already have queued more fixes for 4.14 and they already address the issue, but they are bigger changes that aren't preferable for the late 4.13-rc stage. So, this patch just papers over the bug as a once-off quick fix for a particular ACPI matching. -- tiwai ] Fixes: a36afb0a ("ASoC: rt5677: Introduce proper table for ACPI enumeration") Signed-off-by: Tom Rini <trini@konsulko.com> Acked-by: Mark Brown <broonie@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

For user-defined element set, in its initial state, TLV data is not registered. It's firstly available when any application register it by an additional operation. However, in current implementation, it's available in its initial state. As a result, applications get -ENXIO to read it. This commit controls its readability to manage info flags properly. In an initial state, elements don't have SND_CTL_ELEM_ACCESS_TLV_READ flag. Once TLV write operation is executed, they get the flag.

In a design of ALSA control core, a set of elements is represented by 'struct snd_kcontrol' to share common attributes. The set of elements shares TLV (Type-Length-Value) data, too. On the other hand, in ALSA control interface/protocol for applications, a TLV operation is committed to an element. Totally, the operation can have sub-effect to the other elements in the set. For example, TLV_WRITE operation is expected to change TLV data, which returns to applications. Applications attempt to change the TLV data per element, but in the above design, they can effect to elements in the same set. As a default, ALSA control core has no implementation except for TLV_READ operation. Thus, the above design looks to have no issue. However, in kernel APIs of ALSA control component, developers can program a handler for any request of the TLV operation. Therefore, for elements in a set which has the handler, applications can commit TLV_WRITE and TLV_COMMAND requests. For the above scenario, ALSA control core assist notification. When the handler returns positive value, the core queueing an event for a requested element. However, this includes design defects that the event is not queued for the other element in a set. Actually, developers can program the handlers to keep per-element TLV data, but it depends on each driver. As of v4.13-rc6, there's no driver in tree to utilize the notification, except for user-defined element set. This commit delegates the notification into each driver to prevent developers from the design defects.

Dell laptops have another LED for mic-mute in addition to the master mute. The former is tied with the capture switch (in a reverse way) while the latter is tied with the master playback switch. We already have an enum control to change the behavior for the master mute LED in different ways, e.g. keeping always off or turning off at mute. But, the mic-mute LED has no such management but its behavior is hard-coded. This patch implements an enum control to change the mic-mute LED behavior like what we have for the master mute LED. The ctl provides four modes: keep-on, keep-off, follow-capture and follow-mute. The default mode is the last one, follow-mute, which follows the capture mute, i.e. LED turning on when the capture is off, and turning off when the capture is active.

When user tries to replace the user-defined control TLV, the kernel checks the change of its content via memcmp(). The problem is that the kernel passes the return value from memcmp() as is. memcmp() gives a non-zero negative value depending on the comparison result, and this shall be recognized as an error code. The patch covers that corner-case, return 1 properly for the changed TLV.

MOTU Audio Express is one of third generation in MOTU FireWire series, produced in 2011. This model consists of three chips: * TI TSB41AB2 (Physical layer for IEEE 1394 bus) * Microchip USB3300 (Hi-Speed USB Device with ULPI interface) * Xilinx Spartan-3A FPGA, XC3S400A (Link layer for IEEE 1394 bus, packet processing and data block processing layer) This commit adds support for this model. As I expected, it works with current implementaion of protocol version 3. On the other hand, the unit has a quirk to request subaction originated by any driver. 11:45:51.287643 firewire_ohci 0000:03:00.0: AT spd 2 tl 1f, ffc1 -> ffc0, -reserved-, QW req, fffff0000b14 = 02000200 11:45:51.289193 firewire_ohci 0000:03:00.0: AR spd 2 tl 1f, ffc0 -> ffc1, ack_complete, W resp 11:45:51.289381 fireire_core 0000:03:00.0: unsolicited response (source ffc0, tlabel 1f) 11:45:51.313071 firewire_ohci 0000:03:00.0: AT spd 2 tl 20, ffc1 -> ffc0, ack_pending , QW req, fffff0000b14 = 02000200 11:45:51.314539 firewire_ohci 0000:03:00.0: AR spd 2 tl 20, ffc0 -> ffc1, ack_complete, W resp In 1394 OHCI (rev.1.1), after OUTPUT_LAST* descriptors is processed, 'xferStaus' field is filled with 'ContextControl[0:15]' (see clause 7.1.3). 5 bits in LSB side of the field has ack code in acknowledge from the unit (see clause 7.2.2). A list of the code is shown in Table 3-2. As long as I investigated, in a case of the '-reserved-' acknowledge message from the unit, the field has 0x10. On the table, this value is 'Reserved for definition by future 1394 standards'. As long as I know, any specifications of IEEE 1394 has no such extensions, thus the unit is out of specification. Besides, I note that the unit does not always acknowledge with the invalid code. I guess this is a bug of firmware.

In protocols of MOTU FireWire series, when transferring MIDI messages, transmitter set existence flag to one byte on first several quadlets. The position differs depending on protocols and models, however two cases are confirmed; in 5th byte and 8th byte from MSB side. This commit adds a series of specification flag to describe them. When the existence flag is in the 5th byte, SND_MOTU_SPEC_[R|T]X_MIDI_2ND_Q is used. Else, another set of the flag is used. Here, '_Q' means quadlet.
