Subject: [PATCH AUTOSEL 6.0 33/44] platform/x86: ideapad-laptop: Add module parameters to match DMI quirk tables

From: Hans de Goede <hdegoede@...hat.com>

[ Upstream commit b44fd994e45112b58b6c1dec4451d9a925784589 ]

Add module parameters to allow setting the hw_rfkill_switch and
set_fn_lock_led feature flags for testing these on laptops which are not
on the DMI-id based allow lists for these 2 flags.
