2016-09-27ALSA: hda - Add the top speaker pin config for HP Spectre x360Takashi Iwai1-0/+10
HP Spectre x360 with CX20724 codec has two speaker outputs while the BIOS sets up only the bottom one (NID 0x17) and disables the top one (NID 0x1d). This patch adds a fixup simply defining the proper pincfg for NID 0x1d so that the top speaker works as is.

2016-09-26ALSA: hda - Adding one more ALC255 pin definition for headset problemHui Wang1-0/+4
We have two new Dell laptop models, they have the same ALC255 pin definition, but not in the pin quirk table yet, as a result, the headset microphone can't work. After adding the definition in the table, the headset microphone works well. Cc: <stable@vger.kernel.org> Signed-off-by: Hui Wang <hui.wang@canonical.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-09-25ALSA: usb-line6: use the same declaration as definition in header for MIDI ↵Takashi Sakamoto1-1/+1
manufacturer ID Currently, usb-line6 module exports an array of MIDI manufacturer ID and usb-pod module uses it. However, the declaration is not the definition in common header. The difference is explicit length of array. Although compiler calculates it and everything goes well, it's better to use the same representation between definition and declaration. This commit fills the length of array for usb-line6 module. As a small good sub-effect, this commit suppress below warnings from static analysis by sparse v0.5.0. sound/usb/line6/driver.c:274:43: error: cannot size expression sound/usb/line6/driver.c:275:16: error: cannot size expression sound/usb/line6/driver.c:276:16: error: cannot size expression sound/usb/line6/driver.c:277:16: error: cannot size expression Fixes: 705ececd1c60 ("Staging: add line6 usb driver") Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-09-23ALSA: usb-audio: Extend DragonFly dB scale quirk to cover other variantsAnssi Hannula1-6/+16
The DragonFly quirk added in 42e3121d90f4 ("ALSA: usb-audio: Add a more accurate volume quirk for AudioQuest DragonFly") applies a custom dB map on the volume control when its range is reported as 0..50 (0 .. 0.2dB). However, there exists at least one other variant (hw v1.0c, as opposed to the tested v1.2) which reports a different non-sensical volume range (0..53) and the custom map is therefore not applied for that device. This results in all of the volume change appearing close to 100% on mixer UIs that utilize the dB TLV information. Add a fallback case where no dB TLV is reported at all if the control range is not 0..50 but still 0..N where N <= 1000 (3.9 dB). Also restrict the quirk to only apply to the volume control as there is also a mute control which would match the check otherwise.

We must do it this way, because e.g. POD X3 won't play any sound unless the host listens on the bulk EP, so we cannot export it only via libusb. The driver currently doesn't use the bulk EP messages in other way, in future it could e.g. sense/modify volume(s).

2016-09-09ALSA: hda - Skip Realtek SKU check for Lenovo machinesTakashi Iwai1-0/+2
Realtek codec driver expects an implicit rule where either the codec SSID or the pincfg NID 0x1d contains the some information encoded in some bits. One of the expected information is there is the availability of PC beep, and the driver doesn't build up the PC beep control if this is *supposed* to be disabled there. Meanwhile, Lenovo doesn't seem to follow this requirement (yes it's non-standard after all), and the BIOS sets just the normal SSID and the pincfg values. This resulted in the lack of PC beep on a few machines, purely with a lucky or unlucky number. It didn't bother most people, but some people still demand the PC beep, as found in bug reports. This patch just adds the fixup chain to Lenovo machines to skip the SKU checks. Then the beep control will show up in the mixer, and user can still decide to enable / disable it via the standard mixer interface.

2016-09-08ALSA: rawmidi: Fix possible deadlock with virmidi registrationsound-4.8-rc6Takashi Iwai1-1/+3
When a seq-virmidi driver is initialized, it registers a rawmidi instance with its callback to create an associated seq kernel client. Currently it's done throughly in rawmidi's register_mutex context. Recently it was found that this may lead to a deadlock another rawmidi device that is being attached with the sequencer is accessed, as both open with the same register_mutex.

Just looking at the code I find it likely that there are more problems here such as tu->qhead pointing outside the buffer if the size is changed concurrently using SNDRV_TIMER_IOCTL_PARAMS.

2016-08-31ALSA: fireworks: accessing to user space outside spinlockTakashi Sakamoto4-25/+56
In hwdep interface of fireworks driver, accessing to user space is in a critical section with disabled local interrupt. Depending on architecture, accessing to user space can cause page fault exception. Then local processor stores machine status and handles the synchronous event. A handler corresponding to the event can call task scheduler to wait for preparing pages. In a case of usage of single core processor, the state to disable local interrupt is worse because it don't handle usual interrupts from hardware. This commit fixes this bug, performing the accessing outside spinlock. This commit also gives up counting the number of queued response messages to simplify ring-buffer management.

2016-08-31ALSA: seq: initialize whole fields of automatic variable with union typeTakashi Sakamoto1-2/+5
Currently, automatic variable of 'union ioctl_arg' type is initialized by designated initialization. Although, the actual effect is interpretation of early element of int type and initialization of 'int pversion'. Therefore the first field corresponding to int type is initialized to zero. This is against my expectation to initialize whole fields. This commit uses memset() to initialize the variable, instead of designated initialization.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v4.8 A clutch of fixes for v4.8. These are mainly driver specific, the most notable ones being those for OMAP which fix a series of issues that broke boot on some platforms there when deferred probe kicked in. There's also one core fix for an issue when unbinding a card which for some reason had managed to not manifest until recently.
