Subject: xhci: rename resume_done to resume_timestamp
X-Git-Tag: microblaze-v6.6~1068^2~59
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=a909d629ae77b97b6288bc3cfe68560454bf79c6;p=linux-2.6-microblaze.git

xhci: rename resume_done to resume_timestamp

resume_done is just a timestamp, avoid confusing it with completions
related to port state transitions that are named *_done
