An empty non-removable slot might be the symptom of probing too early.

I took the liberty of adjusting the code and the commit message a bit.
Please let me know if it doesn't look good to you.
So, applied for next, thanks!
Kind regards

Thanks for reviewing & merging.
Can you tell me (for my knowledge) why it's better to check
host->bus_ops than host->card ?
If the situation should not happen, perhaps we should use pr_warn?

It doesn't really matter at this point, but to keep consistency for
some other earlier code in mmc_rescan(), I decided to use
host->bus_ops instead.

Yes, maybe you are right.
In principle, I didn't want to use the warning level as I simply
didn't know if we would end up spamming the log with lots of prints
for various platforms. Perhaps we should change, when we know a bit
more?
Kind regards
