IIRC the reason behind the original "optimization" was to prepare the driver for secondary interrupter support. There was an issue where the secondary interrupters would be lost after resume. The patch was intended to prevent = that by keeping the 'xhci->interrupters' array intact. Thanks, Niklas --=20 You may reply to this email to add a comment.
