ALSA: hda: Hardening for potential Spectre v1

2018-05-23T01:36:38Z

[ Upstream commit 69fa6f19b95597618ab30438a27b67ad93daa7c7 ] As recently Smatch suggested, one place in HD-audio hwdep ioctl codes may expand the array directly from the user-space value with speculation: sound/pci/hda/hda_local.h:467 get_wcaps() warn: potential spectre issue 'codec->wcaps' As get_wcaps() itself is a fairly frequently called inline function, and there is only one single call with a user-space value, we replace only the latter one to open-code locally with array_index_nospec() hardening in this patch.

ALSA: hda/realtek - Always immediately update mute LED with pin VREF

2018-05-23T01:33:52Z

[ Upstream commit e40bdb03d3cd7da66bd0bc1e40cbcfb49351265c ] Some HP laptops have a mute mute LED controlled by a pin VREF. The Realtek codec driver updates the VREF via vmaster hook by calling snd_hda_set_pin_ctl_cache(). This works fine as long as the driver is running in a normal mode. However, when the VREF change happens during the codec being in runtime PM suspend, the regmap access will skip and postpone the actual register change. This ends up with the unchanged LED status until the next runtime PM resume even if you change the Master mute switch. (Interestingly, the machine keeps the LED status even after the codec goes into D3 -- but it's another story.) For improving this usability, let the driver temporarily powering up / down only during the pin VREF change. This can be achieved easily by wrapping the call with snd_hda_power_up_pm() / *_down_pm().

ALSA: hda - Fix headset microphone detection for ASUS N551 and N751

2018-05-23T01:33:49Z

[ Upstream commit fc7438b1eb12b6c93d7b7a62423779eb5dfc673c ] Headset microphone does not work out of the box on ASUS Nx51 laptops. This patch fixes it. Patch tested on Asus N551 laptop. Asus N751 part is not tested, but according to [1] this laptop uses the same audiosystem. 1. https://bugzilla.kernel.org/show_bug.cgi?id=117781 Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=195437 Signed-off-by: Mikhail Paulyshka Signed-off-by: Takashi Iwai Signed-off-by: Sasha Levin

ALSA: hda/realtek - Fix dock line-out volume on Dell Precision 7520

2018-03-21T03:49:50Z

[ Upstream commit e312a869cd726c698a75caca0d9e5c22fd3f1534 ] The dock line-out pin (NID 0x17 of ALC3254 codec) on Dell Precision 7520 may route to three different DACs, 0x02, 0x03 and 0x06. The first two DACS have the volume amp controls while the last one doesn't. And unfortunately, the auto-parser assigns this pin to DAC3, resulting in the non-working volume control for the line out. Fix it by disabling the routing to DAC3 on the corresponding pin. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=199029 Cc: Signed-off-by: Takashi Iwai Signed-off-by: Sasha Levin

ALSA: hda/ca0132 - fix possible NULL pointer use

2018-03-04T15:28:29Z

[ Upstream commit 46a049dae771b95e77ac6c823330f4a60f600236 ] gcc-7 caught what it considers a NULL pointer dereference: sound/pci/hda/patch_ca0132.c: In function 'dspio_scp.constprop': sound/pci/hda/patch_ca0132.c:1487:4: error: argument 1 null where non-null expected [-Werror=nonnull] This is plausible from looking at the function, as we compare 'reply' to NULL earlier in it. I have not tried to analyze if there are constraints that make it impossible to hit the bug, but adding another NULL check in the end kills the warning and makes the function more robust.

ALSA: hda/realtek: PCI quirk for Fujitsu U7x7

2018-03-04T15:28:23Z

[ Upstream commit fdcc968a3b290407bcba9d4c90e2fba6d8d928f1 ] These laptops have a combined jack to attach headsets, the U727 on the left, the U757 on the right, but a headsets microphone doesn't work. Using hdajacksensetest I found that pin 0x19 changed the present state when plugging the headset, in addition to 0x21, but didn't have the correct configuration (shown as "Not connected"). So this sets the configuration to the same values as the headphone pin 0x21 except for the device type microphone, which makes it work correctly. With the patch the configured pins for U727 are Pin 0x12 (Internal Mic, Mobile-In): present = No Pin 0x14 (Internal Speaker): present = No Pin 0x19 (Black Mic, Left side): present = No Pin 0x1d (Internal Aux): present = No Pin 0x21 (Black Headphone, Left side): present = No Signed-off-by: Jan-Marek Glogowski Cc: Signed-off-by: Takashi Iwai Signed-off-by: Sasha Levin

ALSA: hda - Apply the existing quirk to iMac 14,1

2018-03-01T03:09:38Z

[ Upstream commit 031f335cda879450095873003abb03ae8ed3b74a ] iMac 14,1 requires the same quirk as iMac 12,2, using GPIO 2 and 3 for headphone and speaker output amps. Add the codec SSID quirk entry (106b:0600) accordingly.
