Message-ID: <20060201050735.062858000.dtor_core@ameritech.net> (raw)

[-- Attachment #1: tmdc-error-handling.patch --]
[-- Type: text/plain, Size: 1451 bytes --]
Input: tmdc - handle errors from input_register_device()
Also set .owner in driver structure so we'll have a link between
module and driver in sysfs.
