Bartosz Golaszewski 19d61f032c platform/x86: intel: chtwc_int33fe: don't dereference swnode args 
commit 527250cd90 upstream.

Members of struct software_node_ref_args should not be dereferenced
directly but set using the provided macros. Commit d7cdbbc93c
("software node: allow referencing firmware nodes") changed the name of
the software node member and caused a build failure. Remove all direct
dereferences of the ref struct as a fix.

However, this driver also seems to abuse the software node interface by
waiting for a node with an arbitrary name "intel-xhci-usb-sw" to appear
in the system before setting up the reference for the I2C device, while
the actual software node already exists in the intel-xhci-usb-role-switch
module and should be used to set up a static reference. Add a FIXME for
a future improvement.

Fixes: d7cdbbc93c ("software node: allow referencing firmware nodes")
Fixes: 53c24c2932 ("platform/x86: intel_cht_int33fe: use inline reference properties")
