Subject[PATCH] s3c2410_udc: fix custom UDC command handling
From
There is a bug in Samsung's UDC driver, which is completely disabling
the USB device when a custom UDC command is used.
Following patch seems to get the right behavior (e.g. enabling pull-up
instead of disabling then Vcc is applied). Also I'm not in mailing
list so please CC me.

Greetingz,
Vilo
