From: Janne Grunau <j@xxxxxxxxxx>
This is required to allow USB/Bluetooth HID devices to cycle through
platform profiles without depending on ACPI. Commit 52572cde8b4a4
("HID: lenovo: select CONFIG_ACPI_PLATFORM_PROFILE") added this
dependency for hid-lenovo which is used for external USB and Bluetooth
devices.
Fixes: 52572cde8b4a4 ("HID: lenovo: select CONFIG_ACPI_PLATFORM_PROFILE")
