* ALSA: usb-audio - Fix invalid volume resolution on Logitech HD webcam c270Takashi Iwai2013-06-051-0/+1
| | | | | | | | | | | | | | | | USB audio driver spews an error message when probing Logitech HD webcam c270: ALSA mixer.c:1300 usb_audio: Warning! Unlikely big volume range (=6144), cval->res is probably wrong. ALSA mixer.c:1304 usb_audio: [5] FU [Mic Capture Volume] ch = 1, val = 1536/7680/1 Obviously the device needs a fixed volume resolution (cval->res = 384) like other Logitech devices.

* ALSA: hda/via - Fix wrongly cleared pins after suspend on VT1802Takashi Iwai2013-06-031-1/+3
| | | | | | | | | | | | | | | | VIA driver has a special suspend handling only for VT1802 to reduce the pop noise. During the transition to the generic parser, the behavior of snd_hda_set_pin_ctl() was also changed to modify the cached values, too. And this caused a regression where the pin is still cleared even after the resume (including the resume from power save), resulting in the silent output. The fix is simply to replace snd_hda_set_pin_ctl() with the explicit call of snd_hda_codec_write() again.

* ALSA: hda - Add keep_eapd_on flag to generic parserTakashi Iwai2013-06-033-0/+4
| | | | | | | | | | | VT1802 codec seems to reset EAPD of other pins in the hardware level, and this was another reason of the silent headphone output on some machines. As a workaround, introduce a new flag indicating to keep the EPAD on to the generic parser, and set it in patch_via.c.

* ALSA: hda - Allow setting automute/automic hooks after parsingTakashi Iwai2013-06-031-9/+33
| | | | | | | | | | | | | | | | Some codec drivers (VIA codecs and some Realtek fixups) set the automute and automic hooks after calling snd_hda_gen_parse_auto_config(). In the current code, the hook pointers are referred only in snd_hda_gen_parse_auto_config() and passed to snd_hda_jack_detect_enable_callback(), thus changing the hook values won't change the actually called callbacks properly. This patch fixes this bug by setting the static functions as the primary callback functions for the jack detection, and let them calling the appropriate hooks dynamically.

* ALSA: hda/via - Disable broken dynamic power controlTakashi Iwai2013-06-031-0/+5
| | | | | | | | | | | | Since the transition to the generic parser, the actual routes used there don't match always with the assumed static paths in some set_widgets_power_state callbacks. This results in the wrong power setup in the end. As a temporary workaround, we need to disable the calls together with the non-functional dynamic power control enum.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | request_threaded_irq() rejects calls which both do not specify a handler (indicating that the primary IRQ handler should be used) and do not set IRQF_ONESHOT because the combination is unsafe with level-triggered interrupts. It is safe in this case, though, since max98090 IRQs are edge-triggered and the interrupts aren't ACK'ed until the codec's IRQ status register is read. Because of this, an IRQF_ONESHOT interrupt doesn't really make a difference, but request one anyway in order to make request_threaded_irq() happy.

I think it has more potential but still needs work and definately conistency, especiall in its usage. The first thing I come up with is a low hanging fruit regarding devm_ioremap_resouce(). This function already checks if the passed resource is valid and gives an error message if not. So, we can remove similar checks from the drivers and get rid of a bit of code and a number of inconsistent error strings. This series only removes the unneeded check iff devm_ioremap_resource follows platform_get_resource directly. The previous version tried to shuffle code if needed, too, what lead to an embarrasing bug. It turned out to me that shuffling code for all cases found will make the automated script too complex, so I am unsure if an automated cleanup is the proper tool for this case. Removing the easy stuff seems worthwhile to me, though. Despite various architectures and platform dependencies, I managed to compile test 45 out of 57 modified files locally using heuristics and defconfigs."

Some Haswell BIOS will disable the 2nd and 3rd pin/covertor widgets when the HD-A controller changes state from D3 to D0. So when the controller resumes after a system or runtime suspend, these widgets are disabled and programming these widgets to D0 will cause H/W error and codec will not respond. In addition, we found out that some BIOS disables the pins at S3 although it shows up at boot. This confuses the driver utterly, and the hardware falls into the fatal communication error like the above. So in this patch, we apply intel_haswell_enable_all_pins() not only as a fixup to a certain device (with 8086:2010) but to all Haswell machines. The codec driver basically assumes that all pins are exposed, so it's anyway better to see them from the beginning. Even if all pins and converters are shown by this call, there should be no regression in practice: the pin default configurations are still kept, thus the disabled pins are handled as disabled by the driver properly.

| * | ALSA: HDA: Fix Oops caused by dereference NULL pointerWang YanQing2013-05-071-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interrupt handler azx_interrupt will call azx_update_rirb, which may call snd_hda_queue_unsol_event, snd_hda_queue_unsol_event will dereference chip->bus pointer. The problem is we alloc chip->bus in azx_codec_create which will be called after we enable IRQ and enable unsolicited event in azx_probe. This will cause Oops due dereference NULL pointer. I meet it, good luck:) [Rearranged the NULL check before the tracepoint and added another NULL check of bus->workq -- tiwai] Signed-off-by: Wang YanQing <udknight@gmail.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
