The ASUS Zenbook UX425QA_UM425QA fails to initialize the keyboard after a
cold boot.
A quirk already exists for "ZenBook UX425", but some Zenbooks report "Zenbook" with a lowercase 'b'.
Since DMI matching is case-sensitive, the existing quirk is not applied to these "extra special" Zenbooks.
Testing confirms that this model needs the same quirks as the ZenBook UX425 variants.
