fw_devlink will defer the probe until all suppliers are ready. We can't
use builtin_platform_driver_probe() because it doesn't retry after probe
deferral. Convert it to builtin_platform_driver().

If builtin_platform_driver_probe() doesn't work with fw_devlink, then
shouldn't it be fixed or removed?

I was actually thinking about this too. The problem with fixing
builtin_platform_driver_probe() to behave like
builtin_platform_driver() is that these probe functions could be
marked with __init. But there are also only 20 instances of
builtin_platform_driver_probe() in the kernel:
$ git grep ^builtin_platform_driver_probe | wc -l
20

So it might be easier to just fix them to not use
builtin_platform_driver_probe().

Michael,

Any chance you'd be willing to help me by converting all these to
builtin_platform_driver() and delete builtin_platform_driver_probe()?

If it just moving the probe function to the _driver struct and
remove the __init annotations. I could look into that.

Can I drop this patch then ?

No, please pick it up. Michael and I were talking about doing similar
changes for other drivers.
