platform/x86/intel: hid: Add Surface Go to VGBS allow list

2022-06-22T12:27:56+00:00

[ Upstream commit d4fe9cc4ff8656704b58cfd9363d7c3c9d65e519 ]

The Surface Go reports Chassis Type 9 (Laptop,) so the device needs to be
added to dmi_vgbs_allow_list to enable tablet mode when an attached Type
Cover is folded back.

platform/x86/intel: Fix pmt_crashlog array reference

2022-06-22T12:27:56+00:00

[ Upstream commit 66cb3a2d7ad0d0e9af4d3430a4f2a32ffb9ac098 ]

The probe function pmt_crashlog_probe() may incorrectly reference
the 'priv->entry array' as it uses 'i' to reference the array instead
of 'priv->num_entries' as it should.  This is similar to the problem
that was addressed in pmt_telemetry_probe via commit 2cdfa0c20d58
("platform/x86/intel: Fix 'rmmod pmt_telemetry' panic").

platform/x86: hp-wmi: Use zero insize parameter only when supported

2022-06-14T16:45:16+00:00

[ Upstream commit 65f936f3535950d2643eac5bf34a735a0e428cdd ]

commit be9d73e64957 ("platform/x86: hp-wmi: Fix 0x05 error code reported by
several WMI calls") and commit 12b19f14a21a ("platform/x86: hp-wmi: Fix
hp_wmi_read_int() reporting error (0x05)") cause ACPI BIOS Error (bug):
Attempt to CreateField of length zero (20211217/dsopcode-133) because of
the ACPI method HWMC, which unconditionally creates a Field of
size (insize*8) bits:
	CreateField (Arg1, 0x80, (Local5 * 0x08), DAIN)
In cases where args->insize = 0, the Field size is 0, resulting in
an error.

Fix this by using zero insize only if 0x5 error code is returned

Tested on Omen 15 AMD (2020) board ID: 8786.

platform/x86: hp-wmi: Resolve WMI query failures on some devices

2022-06-14T16:45:15+00:00

[ Upstream commit dc6a6ab58379f25bf991d8e4a13b001ed806e881 ]

WMI queries fail on some devices where the ACPI method HWMC
unconditionally attempts to create Fields beyond the buffer
if the buffer is too small, this breaks essential features
such as power profiles:

         CreateByteField (Arg1, 0x10, D008)
         CreateByteField (Arg1, 0x11, D009)
         CreateByteField (Arg1, 0x12, D010)
         CreateDWordField (Arg1, 0x10, D032)
         CreateField (Arg1, 0x80, 0x0400, D128)

In cases where args->data had zero length, ACPI BIOS Error
(bug): AE_AML_BUFFER_LIMIT, Field [D008] at bit
offset/length 128/8 exceeds size of target Buffer (128 bits)
(20211217/dsopcode-198) was obtained.

ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D009] at bit
offset/length 136/8 exceeds size of target Buffer (136bits)
(20211217/dsopcode-198)

The original code created a buffer size of 128 bytes regardless if
the WMI call required a smaller buffer or not.  This particular
behavior occurs in older BIOS and reproduced in OMEN laptops.  Newer
BIOS handles buffer sizes properly and meets the latest specification
requirements.  This is the reason why testing with a dynamically
allocated buffer did not uncover any failures with the test systems at
hand.

This patch was tested on several OMEN, Elite, and Zbooks.  It was
confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN
Laptop 15-ek0xxx.  No problems were reported when testing on several Elite
and Zbooks notebooks.

MIPS: Loongson: Use hwmon_device_register_with_groups() to register hwmon

2022-06-09T08:30:35+00:00

[ Upstream commit abae018a03821be2b65c01ebe2bef06fd7d85a4c ]

Calling hwmon_device_register_with_info() with NULL dev and/or chip
information parameters is an ABI abuse and not a real conversion to
the new API. Also, the code creates sysfs attributes _after_ creating
the hwmon device, which is racy and unsupported to start with. On top
of that, the removal code tries to remove the name attribute which is
owned by the hwmon core.

Use hwmon_device_register_with_groups() to register the hwmon device
instead.

In the future, the hwmon subsystem will reject calls to
hwmon_device_register_with_info with NULL dev or chip/info parameters.
Without this patch, the hwmon device will fail to register.
