uas: ignore UAS for Norelsys NS1068(X) chips
Browse files Browse the repository at this point in the history
commit 928afc8 upstream.

The UAS mode of Norelsys NS1068(X) is reported to fail to work on
several platforms with the following error message:

xhci-hcd xhci-hcd.0.auto: ERROR Transfer event for unknown stream ring slot 1 ep 8
xhci-hcd xhci-hcd.0.auto: @00000000bf04a400 00000000 00000000 1b000000 01098001

And when trying to mount a partition on the disk the disk will
disconnect from the USB controller, then after re-connecting the device
will be offlined and not working at all.

Falling back to USB mass storage can solve this problem, so ignore UAS
function of this chip.
