It's clear from the indent levels and the context that there are supposed to
be curly braces here.

this is a realy nice catch :)
NTL i guess the code is looking for the highest bit that could be replace
with kernel code. (ffs() ?)

just my 2 cents,

It was just a smatch thing.

Well, it's not exactly ffs() because ffs(1) would return 1 but the in
this code when pDevice->wBasicRate is 1 byTopCCK would be 0.

if ( (pDevice->wBasicRate) & ((WORD)(1 << ii)) ) {
if (         1             &        (1 << 1)) { is false.
if (         1             &        (1 << 0)) { is true.

But sure, I can send a patch in the next email.
