2025-01-20platform/x86: acer-wmi: Fix initialization of last_non_turbo_profileArmin Wolf1-15/+26
On machines that do not support the balanced profile the value of last_non_turbo_profile is invalid after initialization which might cause the driver to switch to an unsupported platform profile later. Fix this by only setting last_non_turbo_profile to supported platform profile values.

This patch was used to add TAS2781 devices on SPI support in sound/pci/hda. It use ACPI node descript about parameters of TAS2781 on SPI, it like: Scope (_SB.PC00.SPI0) { Device (GSPK) { Name (_HID, "TXNW2781") // _HID: Hardware ID Method (_CRS, 0, NotSerialized) { Name (RBUF, ResourceTemplate () { SpiSerialBusV2 (...) SpiSerialBusV2 (...) } } } } And in platform/x86/serial-multi-instantiate.c, those spi devices will be added into system as a single SPI device, so TAS2781 SPI driver will probe twice for every single SPI device. And driver will also parser mono DSP firmware binary and RCA binary for itself. The code support Realtek as the primary codec. In patch version-10, add multi devices firmware binary support, to compatble with windows driver, they can share same firmware binary.

2025-01-15Input: i8042 - Add support for platform filter contextsArmin Wolf8-16/+16
Currently the platform filter cannot access any driver-specific state which forces drivers installing a i8042 filter to have at least some kind of global pointer for their filter. Allow callers of i8042_install_filter() to submit a context pointer which is then passed to the i8042 filter. This frees drivers from the responsibility of having to manage this global pointer themself. Also introduce a separate type for the i8042 filter (i8042_filter_t) so that the function definitions can stay compact. Tested on a Dell Inspiron 3505.

2025-01-14platform/x86: lenovo-yoga-tab2-pro-1380-fastcharger: fix serdev raceChenyuan Yang1-2/+3
The yt2_1380_fc_serdev_probe() function calls devm_serdev_device_open() before setting the client ops via serdev_device_set_client_ops(). This ordering can trigger a NULL pointer dereference in the serdev controller's receive_buf handler, as it assumes serdev->ops is valid when SERPORT_ACTIVE is set. This is similar to the issue fixed in commit 5e700b384ec1 ("platform/chrome: cros_ec_uart: properly fix race condition") where devm_serdev_device_open() was called before fully initializing the device. Fix the race by ensuring client ops are set before enabling the port via devm_serdev_device_open(). Note, serdev_device_set_baudrate() and serdev_device_set_flow_control() calls should be after the devm_serdev_device_open() call.

2025-01-09platform/x86: alienware-wmi: Improve hdmi_mux, amplifier and deepslp group ↵Kurt Borja1-76/+38
creation Devices with hdmi_mux, amplifier or deepslp quirks create a sysfs group for each available feature. To accomplish this, helper create/remove functions were called on module init, but they had the following problems: - Create helpers called remove helpers on failure, which in turn tried to remove the sysfs group that failed to be created - If group creation failed mid way, previous successfully created groups were not cleaned up - Module exit only removed hdmi_mux group To improve this, drop all helpers and let the platform driver manage these sysfs groups, while controlling visibility with their respective quirks.
