xhci: Fix resume issues on Renesas chips in Samsung laptops
commit 1aa9578c1a9450fb21501c4f549f5b1edb557e6d upstream.
Don Zickus <dzickus@redhat.com> writes:
Some co-workers of mine bought Samsung laptops that had mostly usb3 ports.
Those ports did not resume correctly (the driver would timeout communicating
and fail). This led to frustration as suspend/resume is a common use for
laptops.
Poking around, I applied the reset on resume quirk to this chipset and the
resume started working. Reloading the xhci_hcd module had been the temporary
workaround.
