I'd just ignore it for now - it seems like there's lots of false positives from this warning which like you say are more global issues and only show up at W=1. signature.asc Description: PGP signature

Hi,
I'm not sure what to do with this report.
I tried to reproduce has instructed, the log is full of warnings and the
compilation eventually fails to link.
It seems that most (if not all) drivers with a MODULE_DEVICE_TABLE() show
this warning with the provided .config (COMPILE_TEST).
When compiled with gcc, no such warning is shown.
I can remove COMPILE_TEST for this driver, it will make the warning go
away but I'm not sure it is appropriate.
