Hi Julian,

Of course but char/u8/s8... allocations never use it and result would be the
factor 1 multiplication.

Those rare occurrences (+- 30 in the whole kernel) where we have
sizeof(u8/s8) is ambiguous.

Having a patch removing it gives a pointer...
If the developer meant something else, he will be able to fix it.
