From 391fa9b1286e89a5b82f26c2efc3df18d72428e5 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Sun, 19 Jul 2009 23:39:56 +0200 Subject: uvcvideo: Add PROBE_DEF quirk and enable it for the MT6227 device From: Laurent Pinchart At least one MT6227 model crashes when receiving a GET_DEF request on the video probe control. As the various models can't be told apart based on the descriptors, add a PROBE_DEF quirk to avoid sending the GET_DEF request and enable the quirk for all models.
