TMDC Joystick no longer works in kernel 2.6.28

TMDC Joystick no longer works in kernel 2.6.28

[Andrew S. Johnson]

Up through kernel version 2.6.27.9 I have had no problems with
my joystick on the game port.  Now with 2.6.28, the game port
is recognized when the gameport and ns558 modules load, but
loading the tmdc module doesn't also automatically load joydev,
and even loading joydev manually doesn't give me a working
joystick.  There are no error messages in dmesg, /var/log/messages, 
or /var/log/syslog.  This is on Slackware 12.1, so I don't think
it's a distro issue.  Do I need to do something different than
in the past to make it work, or is there some debug I can turn
on to give more info?

Please CC me.

Thanks,

If this doesn't get resolved with a few days, please raise a report at
bugzilla.kernel.org, so that we can not fix it in a more organised
fashion, thanks.

The patch below should help with joysticks attached to gameports;
it should appear in 2.6.30-rc3.

Input: gameport - fix attach driver code

The commit 6902c0bead4ce266226fc0c5b3828b850bdc884a that moved
driver registration out of kgameportd thread was incomplete and
did not add the code necessary to actually attach driver to
already registered devices, rectify that.

The TMDC joystick now works under 2.6.30-rc3.  I tested it with 
Google Earth flight simulator, Extreme Tux Racer, and Super Tux 
Kart and it all seems fine.

Thanks for fixing this.
