The prandom_u32() function has been a deprecated inline wrapper around
get_random_u32() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function. The same also applies to get_random_int(), which is
just a wrapper around get_random_u32(). This was done as a basic find
and replace.

mac is defined as u8 mac[ETH_ALEN]; in fwil_types.h.

Nice catch, thanks. Will remove to the get_random_{u16,u8} commit.

But this doesn't make any sense to me. It needs a bit more context:

Why would one change prand wen it will be overwritten in the next loop anyway?

The same code again, and in this case it is impossible to reach, as the check 
already returned false before.

Should these have been something like this in the first place:

	if (prand & 1)
		prand >>=1;
	else
		continue;

At least as the code looks now this only ever needs a single bit of randomness,
and the later checks and the shift can go away, but I suspect that something 
else was meant with that code.

Florian, can you comment and maybe fix it? When possible use prandom_u8() as 
it seems to me that you only need 3 bytes of randomness here anyway.

Or you wanted to move the variable before the loop and keep the random state
between the loops and only reseed when all '1' bits have been consumed. But 
even in this case the later checks seem wrong as the value has not changed in 
between.

Can't comment, do not remember -- this was 5 years ago.

Probably.  No clue, best to NOT change it to not block Jasons series and
then just simplify this and remove all the useless shifts.

Sure. Jason, just in case you are going to do a v7 this could move to u8 then.

Indeed I think this is one to send individually to netdev@ once the tree
opens there for 6.2.
