Input: gtco - fix crash on detecting device without endpoints

2016-06-15T20:28:10+00:00

commit 162f98dea487206d9ab79fc12ed64700667a894d upstream.

The gtco driver expects at least one valid endpoint. If given malicious
descriptors that specify 0 for the number of endpoints, it will crash in
the probe function. Ensure there is at least one endpoint on the interface
before using it.

Also let's fix a minor coding style issue.

The full correct report of this issue can be found in the public
Red Hat Bugzilla:

Input: aiptek - fix crash on detecting device without endpoints

2016-04-01T00:54:37+00:00

commit 8e20cf2bce122ce9262d6034ee5d5b76fbb92f96 upstream.

The aiptek driver crashes in aiptek_probe() when a specially crafted USB
device without endpoints is detected. This fix adds a check that the device
has proper configuration expected by the driver. Also an error return value
is changed to more matching one in one of the error paths.

Input: wacom - relax Bamboo stylus ID check

2012-05-30T23:43:48+00:00

commit c5981411f60c31f0dff6f0f98d2d3711384badaf upstream.

Bit 0x02 always means tip versus eraser. Bit 0x01 is something related
to version of stylus and different values are starting to be used.

Relaxing proximity check is required to be used with 3rd generation
Bamboo Pen and Touch tablets.

Tablet reports a distance of 0 right at highest point possible
to be in proximity and distance_max when touching tablet. Inverse
the distance since user land has no way of knowing ABS_DISTANCE
is not distance from tablet.
