drivers/net: Remove casts of void *

Unnecessary casts of void * clutter the code.

These are the remainder casts after several specific patches to remove netdev_priv and dev_priv.

Unnecessary casts of void * clutter the code. These are the remainder casts after several specific patches to remove netdev_priv and dev_priv.

You seem to have removed a lot of casts that don't relate to these cleanups. In particular, some of the casts seem to relate more to documentation rather than just changing pointer types to make the compiler happy.

In
particular, I'm referring to the casts describing the different usages of data_buf in mwiflex, and around some pointer math in ath9k.

Whilst I'm sure that the compiler is smart enough to handle automatic casts between pointer types, some of these, in particular the mwiflex bits, add some documentation to the code.

You seem to have removed a lot of casts that don't relate to these cleanups. In particular, some of the casts seem to relate more to documentation rather than just changing pointer types to make the compiler happy.

All of the cast removals are casts of void* types. I think none of of the casts are useful. None of them are required, all are duplicative.

Can you describe more in detail why you think these are documentary?

This sort of cast:

I think not. ?Opinions of course can vary.

My issue here is that you mention in the commit log that this relates to the removal of netdev_priv and dev_priv, but the casts removed (mostly) don't.

True, but IMHO, this documents, particularly in a random snippet like this, what's going on. Arguably though, a better fix would be to move the cast to the place where this function is called.

I would never do stuff like this without verifying by sparse that no warnings are introduced.

Sparse warnings should be avoided to keep sparse checks useful. Otherwise, important warnings would drown in the noise.

I did that. I believe there are no new warnings.
