2021-02-24ACPI: platform: Hide ACPI_PLATFORM_PROFILE optionMaximilian Luz
The ACPI_PLATFORM_PROFILE option essentially provides a library and not really an independent module. Thus it seems to be more user-friendly to hide this option and simply make drivers depending on it select it.

Using depends on ensures that platform-profile support is always available when thinkpad_acpi is build, hopefully leading to less confusing bug-reports about it sometimes not working.
