If anyone has any objections, please let me know. ------------------ From: feng commit 2934325f56150ad8dab8ab92cbe2997242831396 upstream. 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.
