USB: atmel-usba-udc : fix control out requests.
usbtest #14 was failing with "udc: ep0: TXCOMP: Invalid endpoint state 2, halting endpoint..." This occured since ep0 is bidirectional and ep->is_in is not valid (must always use ep->state) Signed-off-by: Martin Fuzzey <mfuzzey@gmail.com> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Acked-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
