ALSA: hda - Fix bad dereference of jack object

2016-02-19T22:28:32Z

commit 2ebab40eb74a0225d5dfba72bfae317dd948fa2d upstream. The hda_jack_tbl entries are managed by snd_array for allowing multiple jacks. It's good per se, but the problem is that struct hda_jack_callback keeps the hda_jack_tbl pointer. Since snd_array doesn't preserve each pointer at resizing the array, we can't keep the original pointer but have to deduce the pointer at each time via snd_array_entry() instead. Actually, this resulted in the deference to the wrong pointer on codecs that have many pins such as CS4208. This patch replaces the pointer to the NID value as the search key. As an unexpected good side effect, this even simplifies the code, as only NID is needed in most cases. Signed-off-by: Takashi Iwai Signed-off-by: Greg Kroah-Hartman

ALSA: hda - Fix speaker output from VAIO AiO machines

2016-02-19T22:28:32Z

commit c44d9b1181cf34e0860c72cc8a00e0c47417aac0 upstream. Some Sony VAIO AiO models (VGC-JS4EF and VGC-JS25G, both with PCI SSID 104d:9044) need the same quirk to make the speaker working properly.

Revert "ALSA: hda - Fix noise on Gigabyte Z170X mobo"

2016-02-19T22:28:32Z

commit 6c361d10e0eb859233c71954abcd20d2d8700587 upstream. This reverts commit 0c25ad80408e95e0a4fbaf0056950206e95f726f. The original commit disabled the aamixer path due to the noise problem, but it turned out that some mobo with the same PCI SSID doesn't suffer from the issue, and the disabled function (analog loopback) is still demanded by users. Since the recent commit [e7fdd52779a6: ALSA: hda - Implement loopback control switch for Realtek and other codecs], we have the dynamic mixer switch to enable/disable the aamix path, and we don't have to disable the path statically any longer. So, let's revert the disablement, so that only the user suffering from the noise problem can turn off the aamix on the fly.

ALSA: hda - Fix static checker warning in patch_hdmi.c

2016-02-19T22:28:32Z

commit 360a8245680053619205a3ae10e6bfe624a5da1d upstream. The static checker warning is: sound/pci/hda/patch_hdmi.c:460 hdmi_eld_ctl_get() error: __memcpy() 'eld->eld_buffer' too small (256 vs 512) I have a hard time figuring out if this can ever cause an information leak (I don't think so), but nonetheless it does not hurt to increase the robustness of the code.

ALSA: hda - Add fixup for Mac Mini 7,1 model

2016-02-19T22:28:32Z

commit 2154cc0e2d4ae15132d005d17e473327c70c9a06 upstream. Mac Mini 7,1 model with CS4208 codec reports the headphone jack detection wrongly in an inverted way. Moreover, the advertised pins for the audio input and SPDIF output have actually no jack detection. This patch addresses these issues. The inv_jack_detect flag is set for fixing the headphone jack detection, and the pin configs for audio input and SPDIF output are marked as non-detectable.

ALSA: hda - Implement loopback control switch for Realtek and other codecs

2016-02-19T22:28:23Z

commit e7fdd52779a6c2b49d457f452296a77c8cffef6a upstream. Many codecs, typically found on Realtek codecs, have the analog loopback path merged to the secondary input of the middle of the output paths. Currently, we don't offer the dynamic switching in such configuration but let each loopback path mute by itself. This should work well in theory, but in reality, we often see that such a dead loopback path causes some background noises even if all the elements get muted. Such a problem has been fixed by adding the quirk accordingly to disable aamix, and it's the right fix, per se. The only problem is that it's not so trivial to achieve it; user needs to pass a hint string via patch module option or sysfs. This patch gives a bit improvement on the situation: it adds "Loopback Mixing" control element for such codecs like other codecs (e.g. IDT or VIA codecs) with the individual loopback paths. User can turn on/off the loopback path simply via a mixer app. For keeping the compatibility, the loopback is still enabled on these codecs. But user can try to turn it off if experiencing a suspicious background or click noise on the fly, then build a static fixup later once after the problem is addressed. Other than the addition of the loopback enable/disablement control, there should be no changes. Signed-off-by: Takashi Iwai Signed-off-by: Greg Kroah-Hartman

ALSA: hda - Flush the pending probe work at remove

2016-01-31T19:25:48Z

commit 991f86d7ae4e1f8c15806e62f97af519e3cdd860 upstream. As HD-audio driver does deferred probe internally via workqueue, the driver might go into the mixed state doing both probe and remove when the module gets unloaded during the probe work. This eventually triggers an Oops, unsurprisingly. For avoiding this race, we just need to flush the pending probe work explicitly before actually starting the resource release.
