It's mostly controlled by probing order. This can be problematic if one driver changes CPU settings and another driver notifies the EC for changing fan curves. Modify the ACPI platform profile handler to let multiple drivers register platform profile handlers and abstract this detail from userspace. To avoid undefined behaviors only offer profiles that are commonly advertised across multiple handlers. If any problems occur when changing profiles for any driver, then the drivers that were already changed remain changed and the legacy sysfs handler will report 'custom'.
