-Subject: HID: rmi: check sanity of the incoming report
-
-In the Dell XPS 13 9333, it appears that sometimes the bus get confused
-and corrupts the incoming data. It fills the input report with the
-sentinel value "ff". Synaptics told us that such behavior does not comes
-from the touchpad itself, so we filter out such reports here.
-
-Unfortunately, we can not simply discard the incoming data because they
-may contain useful information. Most of the time, the misbehavior is
-quite near the end of the report, so we can still use the valid part of
-it.
