You are quite correct. I previously failed to read your code as good as I
should have :-( Sorry about that.

First, are you sure that platform_device_register actually succeeds?

The times this has happened to me, it has always been a problem with the
"name" between the platform device and the platform driver.

To avoid those problems, I usually use a #define for the name. That way,
I'm sure that a spelling problem (which can be _really_ hard to spot)  is
not the problem. Also, I usually don't care about setting the .id and the
.num_resources variables.

Otherwise, as far as I can tell, your code should work.

BRs,
/Jocke!
