commit e735e957f2b9cfe4be486e0304732ec36928591f upstream.
Since commit f8f80be501aa ("xhci: Use soft retry to recover faster from transaction errors"), unplugging USB device while enumeration results in errors like this:
[ 364.855321] xhci_hcd 0000:0b:00.0: ERROR Transfer event for disabled endpoint slot 5 ep 2 [ 364.864622] xhci_hcd 0000:0b:00.0: @0000002167656d70 67f03000 00000021 0c000000 05038001 [ 374.934793] xhci_hcd 0000:0b:00.0: Abort failed to stop command ring: -110 [ 374.958793] xhci_hcd 0000:0b:00.0: xHCI host controller not responding, assume dead [ 374.967590] xhci_hcd 0000:0b:00.0: HC died; cleaning up [ 374.973984] xhci_hcd 0000:0b:00.0: Timeout while waiting for configure endpoint command
Seems that Etorn xHCI host can not perform Soft Retry correctly, apply XHCI_NO_SOFT_RETRY quirk to disable Soft Retry and then issue is gone.
This patch depends on commit a4a251f8c235 ("usb: xhci: do not perform Soft Retry for some xHCI hosts").
