I realized one thing today: your "From" address (gmail) doesn't match your SoB address (wacom). I still applied the patch because we used to not care about that for your patches, but this raises a useless checkpatch.pl warning (and I am scrutinizing any incoming patches with checkpatch.pl starting from now). Can you fix your pipeline?

The 'wacom_hid_usage_quirk' function is the intended home for fixing up descriptors that are buggy or that don't quite fit the mold. Commit 578325120e was supposed to move all of these quirks but it missed the code to handle fixup the serial number usages for AES pens. Lets move this code out of 'wacom_wac_pen_usage_mapping' where it was previously lurking and put it into the same place as the others.
