Input: gtco - fix crash on detecting device without endpoints

2016-06-07T08:42:51+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.

Input: wacom - make sure touch_max is set for touch devices

2014-03-31T16:58:14+00:00

commit 1d0d6df02750b4a6f466768cbfbf860e24f4c8d4 upstream.

Old single touch Tablet PCs do not have touch_max set at
wacom_features. Since touch device at lease supports one
finger, assign touch_max to 1 when touch usage is defined
in its HID Descriptor and touch_max is not pre-defined.
