You should add:
Fixes: 8bdfa145f582 ("PCI: sysfs: Define device attributes with DEVICE_ATTR*()")
Fixes: 4e2b79436e4f ("PCI: sysfs: Change DEVICE_ATTR() to DEVICE_ATTR_WO()")

to this too, and a
Cc: stable <stable@xxxxxxxxxxxxxxx>
to the signed-off-by: area so that it gets properly backported.

Other than that minor thing, looks good to me, thanks for fixing it so
