2014-03-07ALSA: hda - Fix loud click noise with IdeaPad 410YTakashi Iwai
Lenovo IdeaPad 410Y with ALC282 codec makes loud click noises at boot and shutdown. Also, it wrongly misdetects the acpi_thinkpad hook. This patch adds a device-specific fixup for disabling the shutup callback that is the cause of the click noise and also avoiding the thinpad_helper calls.

2014-02-10ALSA: hda - Fix undefined symbol due to builtin/module mixupTakashi Iwai
Even after the fix for leftover kconfig handling (commit f8f1becf), the current code still doesn't handle properly the builtin/module mixup case between the core snd-hda-codec and other codec drivers. For example, when CONFIG_SND_HDA_INTEL=y and CONFIG_SND_HDA_CODEC_HDMI=m, it'll end up with an unresolved symbol snd_hda_parse_hdmi_codec. This patch fixes the issue. Now codec->parser points to the parser object *only* when a module (either generic or HDMI parser) is loaded and bound. When a builtin symbol is used, codec->parser still points to NULL. This is the difference from the previous versions.

2014-02-07ALSA: hda - Fix inconsistent Mic mute LEDTakashi Iwai
The current code for controlling mic mute LED in patch_sigmatel.c blindly assumes that there is a single capture switch. But, there can be multiple multiple ones, and each of them flips the state, ended up in an inconsistent state. For fixing this problem, this patch adds kcontrol to be passed to the hook function so that the callee can check which switch is being accessed.

2014-01-31ALSA: hda/hdmi - allow PIN_OUT to be dynamically enabledStephen Warren
Commit 384a48d71520 "ALSA: hda: HDMI: Support codecs with fewer cvts than pins" dynamically enabled each pin widget's PIN_OUT only when the pin was actively in use. This was required on certain NVIDIA CODECs for correct operation. Specifically, if multiple pin widgets each had their mux input select the same audio converter widget and each pin widget had PIN_OUT enabled, then only one of the pin widgets would actually receive the audio, and often not the one the user wanted! However, this apparently broke some Intel systems, and commit 6169b673618b "ALSA: hda - Always turn on pins for HDMI/DP" reverted the dynamic setting of PIN_OUT. This in turn broke the afore-mentioned NVIDIA CODECs. This change supports either dynamic or static handling of PIN_OUT, selected by a flag set up during CODEC initialization. This flag is enabled for all recent NVIDIA GPUs.

2013-12-19ALSA: hda - Make CONFIG_SND_HDA_CODEC_* tristateTakashi Iwai
So far, CONFIG_SND_HDA_CODEC_* kconfigs have been booleans due to historical reasons. The major reason was that the automatic codec driver probing wouldn't work if user sets a codec driver as a module while the controller driver as a built-in. And, another reason was to avoid exporting symbols of the helper codes when all drivers are built in. But, this sort of "kindness" rather confuses people in the end, especially makes the config refinement via localmodconfig unhappy. Also, a codec module would still work if you re-bind the controller driver via sysfs (although it's no automatic loading), so there might be a slight use case. That said, better to let people fallen into a pitfall than being too smart and restrict something. Let's make things straightforward: now all CONFIG_SND_HDA_CODEC_* become tristate, and all symbols exported unconditionally. Signed-off-by: Takashi Iwai <tiwai@suse.de>
