USB: xhci: Setup HW retries correctly.
The xHCI host controller can be programmed to retry a transfer a certain number of times per endpoint before it passes back an error condition to the host controller driver. The xHC will return an error code when the error count transitions from 1 to 0. Programming an error count of 3 means the xHC tries the transfer 3 times, programming it with a 1 means it tries to transfer once, and programming it with 0 means the HW tries the transfer infinitely. We want isochronous transfers to only be tried once, so set the error count to one. Signed-off-by: Sarah Sharp <firstname.lastname@example.org> Signed-off-by: Greg Kroah-Hartman <email@example.com>
