platform/x86: intel: int1092: intel_sar: Convert to platform remove callback returning void

2023-03-07T11:20:31Z

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 (mostly) ignored 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. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

platform/x86: int1092: Switch to use acpi_evaluate_dsm_typed()

2023-02-02T21:48:20Z

The acpi_evaluate_dsm_typed() provides a way to check the type of the object evaluated by _DSM call. Use it instead of open coded variant.

platform/x86: int1092: Fix non sequential device mode handling

2021-10-11T14:39:25Z

SAR information from BIOS may come in non sequential pattern. To overcome the issue, a check is made to extract the right SAR information using the device mode which is currently being used. Remove .owner field if calls are used which set it automatically.

platform/x86: BIOS SAR driver for Intel M.2 Modem

2021-08-20T10:09:41Z

Dynamic BIOS SAR driver exposing dynamic SAR information from BIOS The Dynamic SAR (Specific Absorption Rate) driver uses ACPI DSM (Device Specific Method) to communicate with BIOS and retrieve dynamic SAR information and change notifications. The driver uses sysfs to expose this data to userspace via read and notify. Sysfs interface is documented in detail under: Documentation/ABI/testing/sysfs-driver-intc_sar Signed-off-by: Shravan S Link: https://lore.kernel.org/r/20210723211452.27995-2-s.shravan@intel.com Reviewed-by: Hans de Goede Signed-off-by: Hans de Goede
