Subject: [PATCH] usb: typec: Remove retimers properly
Git-commit: b7cafb8b06a05c146bf75e5f666f8d84191d1ad4
References: jsc#PED-1211
Patch-mainline: v6.0-rc4

Retimer device class is left dangling when the typec module
is unloaded. Attempts to reload the module failed with warning:

        "sysfs: cannot create duplicate filename '/class/retimer'"

Fixing the issue by unregistering the class properly.

Fixes: ddaf8d96f93b ("usb: typec: Add support for retimers")
