[PATCH v9 03/22] ACPI: platform_profile: Add device pointer into platform profile handler

Mario Limonciello
2024-12-02T05:51:39Z

In order to let platform profile handlers manage platform profile
for their driver the core code will need a pointer to the device.

Add this to the structure and use it in the trivial driver cases.
