Commit Message

Jens reported that the sanity checks added to the new ps883x USB retimer
driver breaks USB and display on the HP X14. Turns out the X14 only has
a retimer on one of the ports, but this initially went unnoticed due to
the missing sanity check (and error handling) in the retimer driver.

Drop the non-existing retimer from the devicetree to enable the second
USB port and the display subsystem.

Note that this also matches the ACPI tables.

Fixes: 6f18b8d4142c ("arm64: dts: qcom: x1e80100-hp-x14: dt for HP Omnibook X Laptop 14")

The devicetree went upstream before the retimer driver so the display
would already be broken in 6.14 and there's no need to backport this
one (but it should go into 6.15).

Note that the SBU mux can be added later when/if someone figures out how
it is connected.

Johan
