A note to the backlight class / subsystem maintainers, this change
applies on top of a similar patch for drivers/platform/x86
version of the Yoga Book uses completely different DMI strings.
Also adjust the X91F/L quirk to reflect that it only applies to
the X91F/L models.

This fixes a regression in 6.1, adding the regressions list to the Cc.
