From: David Brownell <[EMAIL PROTECTED]>
Some of the "EHCI ports reset forever" problems may be explained by
code paths which wrongly flagged resets as complete. This removes
two such paths; the ehci_hub_status_data() path should be the only one
to have an effect, since it was already properly flagged on the other
path. (Issue noted by Minhyoung Kim <[EMAIL PROTECTED]>.)
