USB: dummy-hcd: accept mismatch between wLength and transfer length
This patch (as1269) fixes a bug in the way dummy_hcd handles control URBs. Currently it returns a -EOVERFLOW error if the wLength value in the setup packet is different from the URB's transfer_buffer_length. Other host controller drivers don't do this. There's no reason the two length values have to be equal, and in fact they sometimes aren't -- a driver might set the transfer length to the maxpacket value in order to handle buggy devices that don't respect wLength. This patch simply removes the unnecessary check and error return. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
