USB: gadget: s3c2410_udc uses standard GPIO calls
Change the gpio code in the s3c2410_udc to use the generic gpio calls instead of the s3c24xx specific gpio functions. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
