2023-12-11platform/x86/intel/tpmi: Modify external interface to get read/write stateSrinivas Pandruvada
Modify the external interface tpmi_get_feature_status() to get read and write blocked instead of locked and disabled. Since auxiliary device is not created when disabled, no use of returning disabled state. Also locked state is not useful as feature driver can't use locked state in a meaningful way. Using read and write state, feature driver can decide which operations to restrict for that feature.

2023-12-11platform/x86/intel/tpmi: Don't create devices for disabled featuresSrinivas Pandruvada
If some TPMI features are disabled, don't create auxiliary devices. In this way feature drivers will not load. While creating auxiliary devices, call tpmi_read_feature_status() to check feature state and return if the feature is disabled without creating a device.

2023-12-11platform/x86: hp-wmi: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

Pro YT3-X90F Fix the maximum brightness being much too low on the Yoga Tab 3 Pro. The LP8557 backlight controller can either be configured to multiply its PWM input and the I2C register set level (requiring both to be at 100% for 100% output); or to only take the I2C register set level into account. Multiplying the 2 levels is useful because this will turn off the backlight when the panel goes off and turns off its PWM output. But on the YT3-X90F the panel's PWM output defaults to a duty-cycle of much less then 100%, severely limiting max brightness. In this case the LP8557 should be configured to only take the I2C register into account and the i915 driver must turn off the backlight separately using a VBT MIPI sequence to turn off the backlight.

2023-11-20ACPI: scan: Add LNXVIDEO HID to ignore_serial_bus_ids[]Hans de Goede
The I2C-core already has filtering to skip i2c_client instantiation for LNXVIDEO acpi_device-s with I2cSerialBus resources, since LNXVIDEO devices are not i2c_client-s and are handled by the acpi_video driver. This filtering was added to i2c-core-acpi.c in commit 3a4991a9864c ("i2c: acpi: Do not create i2c-clients for LNXVIDEO ACPI devices"). Now a similar problem has shown up where the SPI-core is instantiating an unwanted SPI-device for a SpiSerialBus resource under a LNXVIDEO acpi_device. On a Lenovo Yoga Tab 3 YT3-X90F this unwanted SPI-device instanstantiation causes the SPI-device instanstantiation for the WM5102 audio codec to fail with: [ 21.988441] pxa2xx-spi 8086228E:00: chipselect 0 already in use Instead of duplicating the I2C-core filtering in the SPI-core code, push the filtering of SerialBus resources under LNXVIDEO acpi_device-s up into the ACPI-core by adding the LNXVIDEO HID to ignore_serial_bus_ids[]. Note the filtering in the I2C-core i2c_acpi_do_lookup() function is still necessary because this not only impacts i2c_client instantiation but it also makes the I2C-core ignore the I2cSerialBus resource when checking what the maximum speed is the I2C bus supports, which is still necessary.
