  staging: rtl8723bs: Convert LIST_CONTAINOR to use kernel container_of
  staging: rtl8723bs: Convert LIST_CONTAINOR to container_of

This is basically a simple substitution of a spelling typo of a macro
with an addition to simplify some odd uses of the macro.

I have no objection to this being deferred if it interferes with other
more important changes.

This whole driver seems like it a fair amount of work before it could
be merged into mainline.

[PATCH 1/2] staging: rtl8723bs: Convert LIST_CONTAINOR to use kernel container_of

[Joe Perches]

These are similar macros so use the normal kernel one.

As well, there are odd games being played with casting a plist to
a union recv_frame by using LIST_CONTAINOR.  Just use a direct cast
to union recv_frame instead.

No, you are "assuming" that the list_head is going to stay the first
object of this structure, and what if it isn't?

Just use container_of, that way at least you get the type safeness of
the call, and if something changes in the future, you don't instantly
break the code everywhere without knowing it.

It's a named union u and it's exactly at the beginning.
It's unlikely to change.

The container_of macro doesn't work here as there it has
a BUILD_BUG_ON_MSG and there are pointer type mismatches
on those uses.

Yeah, but random pointer casts like this are not good, I don't want to
see that here, sorry.

Fix up the pointer mismatches, if there are any, as that implies there
are bugs here...

<shrug>.

No thanks.

That's what the current code is doing now.

Ignore the whole thing if you want.

Someone else might fix it eventually, but more
likely the current rtl8723bs driver will be
dropped and completely rewritten anyway.

[PATCH 2/2] staging: rtl8723bs: Convert LIST_CONTAINOR to container_of

[Joe Perches]

Use the normal kernel macro.
Remove the now ununsed LIST_CONTAINOR macro.
