Revert "xHCI: reset-on-resume quirk for NEC uPD720200"
This reverts commit
d10defae1e3b77c6f33b3eee637ec10efab95e43.
The commit added a reset-on-resume quirk because the NEC chipset stopped
responding to commands about 30 minutes after a system resume from
suspend. We thought it was a chipset issue, but it turns out that the
xHCI driver was zeroing out the link TRB after a successful context
restore during resume. The host controller would fall off the command
ring sometime later, causing it to not respond to new commands.
The link TRB issue has been fixed with commit
6490c199bb41f292ebf0afcaf1c0531068dde83f "xHCI: fix bug in
xhci_clear_command_ring()", so revert the reset-on-resume quirk, as it's
not necessary.
