[PATCH v10 04/22] ACPI: platform_profile: Add platform handler argument to platform_profile_remove()

Mario Limonciello
2024-12-06T03:23:43Z

To allow registering and unregistering multiple platform handlers calls
to platform_profile_remove() will need to know which handler is to be
removed. Add an argument for this.
