+From: Peter Hutterer <peter.hutterer at who-t.net>

+From: Niels Ole Salscheider <niels_ole at salscheider-online.de>
+
+Catch the error case separately. Commit 19a9cd607d added length checking to
+SizeClassInfo but re-used the return value of 0 for an error. A device without
+classes (as is initialized by xf86-input-libinput for tablets) can
+legitimately return 0 and erroneously triggers an error.
+Fix this by using a separate value for the error.
+
+Reproducible by calling XListInputDevices() with a tablet attached.
+
+This fixes a regression introduced in commit 19a9cd607d.

+We used to always set *ndevices to the number of devices returned by the

+except on faulty server or library implementations. With 19a9cd60 we now have
+more chances of getting an error, so the polite thing is to just leave *ndevices

+
+Document it as such in the man page, just in case someone accidentally reads
