[PATCH v3 03/22] ACPI: platform_profile: Add device pointer into platform profile handler
Posted by Mario Limonciello 3 weeks, 3 days ago 
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.
