Subject: cxl: Rename 'uport' to 'uport_dev'
From: Dan Williams <dan.j.williams@...el.com>
For symmetry with the recent rename of ->dport_dev for a 'struct
cxl_dport', add the "_dev" suffix to the ->uport property of a 'struct
cxl_port'. These devices represent the downstream-port-device and
upstream-port-device respectively in the CXL/PCIe topology.
