1aa0ec5cdf iwlwifi: dvm: don't call << operator with a negative value 
In https://bugzilla.kernel.org/show_bug.cgi?id=177341 Bob
reported a UBSAN WARNING on rs.c.

Undefined behaviour in drivers/net/wireless/intel/iwlwifi/dvm/rs.c:746:18

This because
	i = index - 1;
	for (mask = (1 << i); i >= 0; i--, mask >>= 1)

is unsafe: i could be negative and hence we can call <<
on a negative value.
This bug doesn't have any real impact since the condition
of the for loop will prevent any usage of mask.

ad04e088d4 iwlwifi: dvm: make rs_tl_get_load() return void 
The return value from this function is never used, so make it return
void to avoid getting the following warning when compiling wiht W=1:

57fbcce37b cfg80211: remove enum ieee80211_band 
This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.
