USB: usbtest.c: unsigned retval makes ctrl_out return 0 in case of error
In my quest to try and figure out why test 14 (control write) doesn't work with my EZ-USB board, I noticed that sometimes testusb reported no error even though the kernel log complained "byte 0 is 0 not 2" etc. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
