platform/x86: dell-privacy: Fix SW_CAMERA_LENS_COVER reporting
Use KE_VSW instead of KE_SW for the SW_CAMERA_LENS_COVER key_entry and get the value of the switch from the status field when handling SW_CAMERA_LENS_COVER events, instead of always reporting 0. Also correctly set the initial SW_CAMERA_LENS_COVER value. Fixes: 8af9fa37b8a3 ("platform/x86: dell-privacy: Add support for Dell hardware privacy") Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20221221220724.119594-1-hdegoede@redhat.com
