mtd: fixup CFI on ixp4xx

2022-01-20T08:17:52+00:00

commit 603362b4a58393061dcfed1c7f0d0fd4aba61126 upstream. drivers/mtd/maps/ixp4xx.c requires MTD_CFI_BE_BYTE_SWAP to be set in order to compile. drivers/mtd/maps/ixp4xx.c:57:4: error: #error CONFIG_MTD_CFI_BE_BYTE_SWAP required This patch avoids the #error output by enforcing the policy in Kconfig. Not sure if this is the right approach, but it helps doing randconfig builds.

ALSA: hda/realtek: Re-order quirk entries for Lenovo

commit 2aac550da3257ab46e8c7944365eb4a79ccbb3a1 upstream. The recent few quirk entries for Lenovo haven't been put in the right order. Let's arrange the table again.

ALSA: hda/realtek: Add quirk for Legion Y9000X 2020

2022-01-20T08:17:51+00:00

commit 8f4c90427a8f0ca0fcdd89d8966fcdab35fb2d4c upstream. Legion Y9000X 2020 has a speaker, but the speaker doesn't work. This can be fixed by applying alc285_fixup_ideapad_s740_coef to fix the speaker's coefficients. Besides, to support the transition between the speaker and the headphone, alc287_fixup_legion_15imhg05_speakers needs to be run.

ALSA: hda: ALC287: Add Lenovo IdeaPad Slim 9i 14ITL5 speaker quirk

2022-01-20T08:17:51+00:00

commit b81e9e5c723de936652653241d3dc4f33ae05e8c upstream. The speaker fixup that is used for the Yoga 7 14ITL5 also applies to the IdeaPad Slim 9i 14ITL5. The attached patch applies the quirk to initialise the amplifier on the IdeaPad Slim 9i as well. This is validated to work on my laptop.

ALSA: hda/realtek - Fix silent output on Gigabyte X570 Aorus Master after reboot from Windows

2022-01-20T08:17:51+00:00

commit c1933008679586b20437280463110c967d66f865 upstream. This patch addresses an issue where after rebooting from Windows into Linux there would be no audio output. It turns out that the Realtek Audio driver on Windows changes some coeffs which are not being reset/reinitialized when rebooting the machine. As a result, there is no audio output until these coeffs are being reset to their initial state. This patch takes care of that by setting known-good (initial) values to the coeffs. We initially relied upon alc1220_fixup_clevo_p950() to fix some pins in the connection list. However, it also sets coef 0x7 which does not need to be touched. Furthermore, to prevent mixing device-specific quirks I introduced a new alc1220_fixup_gb_x570() which is heavily based on alc1220_fixup_clevo_p950() but does not set coeff 0x7 and fixes the coeffs that are actually needed instead. This new alc1220_fixup_gb_x570() is believed to also work for other boards, like the Gigabyte X570 Aorus Extreme and the newer Gigabyte Aorus X570S Master. However, as there is no way for me to test these I initially only enable this new behaviour for the mainboard I have which is the Gigabyte X570(non-S) Aorus Master. I tested this patch on the 5.15 branch as well as on master and it is working well for me.

ALSA: hda/realtek: Add speaker fixup for some Yoga 15ITL5 devices

KVM: x86: remove PMU FIXED_CTR3 from msrs_to_save_all

2022-01-20T08:17:51+00:00

commit 9fb12fe5b93b94b9e607509ba461e17f4cc6a264 upstream. The fixed counter 3 is used for the Topdown metrics, which hasn't been enabled for KVM guests. Userspace accessing to it will fail as it's not included in get_fixed_pmc(). This breaks KVM selftests on ICX+ machines, which have this counter. To reproduce it on ICX+ machines, ./state_test reports: ==== Test Assertion Failure ==== lib/x86_64/processor.c:1078: r == nmsrs pid=4564 tid=4564 - Argument list too long 1 0x000000000040b1b9: vcpu_save_state at processor.c:1077 2 0x0000000000402478: main at state_test.c:209 (discriminator 6) 3 0x00007fbe21ed5f92: ?? ??:0 4 0x000000000040264d: _start at ??:?

firmware: qemu_fw_cfg: fix kobject leak in probe error path

2022-01-20T08:17:51+00:00

commit 47a1db8e797da01a1309bf42e0c0d771d4e4d4f3 upstream. An initialised kobject must be freed using kobject_put() to avoid leaking associated resources (e.g. the object name). Commit fe3c60684377 ("firmware: Fix a reference count leak.") "fixed" the leak in the first error path of the file registration helper but left the second one unchanged. This "fix" would however result in a NULL pointer dereference due to the release function also removing the never added entry from the fw_cfg_entry_cache list. This has now been addressed. Fix the remaining kobject leak by restoring the common error path and adding the missing kobject_put().
