Subject: [PATCH] usb: dwc3: host: Stop setting the ACPI companion
Git-commit: 7fd069d65da2e20b1caec3b7bcf9dfbe28c04bb2
References: jsc#PED-1817
Patch-mainline: v5.19-rc1

It is no longer needed. The sysdev pointer is now used when
assigning the ACPI companions to the xHCI ports and USB
devices.

Assigning the ACPI companion here resulted in the
fwnode->secondary pointer to be replaced also for the parent
dwc3 device since the primary fwnode (the ACPI companion)
was shared. That was unintentional and it created potential
side effects like resource leaks.
