Subject: [PATCH] s3c2410_udc: udc command always disables pull-up instead of
 passing the command

Hello *,

Sorry for the HTML,
There is a bug in s3c2410_udc driver, which triggers when using custom
UDC command for USB pull-up.
As a result driver is always calling user defined UDC command with
wrong parameter (S3C2410_UDC_P_DISABLE) instead of
just passing the parameter to the user defined function.

BR.

Vilo
