Subject: [PATCH AUTOSEL 5.4 11/73] HID: apple: Do not reset quirks when the Fn key is not found

From: José Expósito <jose.exposito89@...il.com>

[ Upstream commit a5fe7864d8ada170f19cc47d176bf8260ffb4263 ]

When a keyboard without a function key is detected, instead of removing
all quirks, remove only the APPLE_HAS_FN quirk.
