[PATCH 0/2] platform/x86: hp-wmi: Modernize driver API and perform_query()

From: yahia ahmed <[email protected]>

Refactor various parts of hp-wmi, including hp_wmi_perform_query() and 
encode_outsize_for_pvsz(), to adopt modern kernel APIs, resource cleanup
attributes, and buffer bounds safety checks.

Patch 1 migrates the hp-wmi driver from the deprecated wmi_evaluate_method()
API to the modern wmidev_evaluate_method() function by registering as a
WMI driver.

Patch 2 refactors encode_outsize_for_pvsz() with a switch statement, adds
early ACPI return buffer length validation to prevent potential integer
underflow in hp_wmi_perform_query(), replaces kmalloc with kzalloc_flex
to zero memory, and use __free() macro to free variables.

yahia (2):
  hp-wmi: Modernize hp_wmi_perform_query() to use the modern API
  hp-wmi: use modern cleanup and refactor allocation functions
