2d9d238511 b43: mark some functions and structs static 
This fixes some sparse warnings.

2e1253d640 b43: N-PHY: use more bits for offset in RSSI calibration 
When calculating "offset" for final RSSI calibration we're using numbers
bigger than s8 can hold. We have for example:
offset[j] = 232 - poll_results[j];
formula. If poll_results[j] is small enough (it usually is) we treat
number's bit as a sign bit. For example 232 - 1 becomes:
0xE8 - 0x1 = 0xE7, which is not 231 but -25.

This code was introduced in e0c9a0219a
and caused stability regression on some cards, for ex. BCM4322.

e67dd874e6 b43: N-PHY: increase initial value of "mind" in RSSI calibration 
We're using "mind" variable to find the VCM that got the best polling
results. For each VCM we calculte "currd" which is compared to the
"mind". For PHY rev3+ "currd" gets values around 14k-40k. Looking for a
value smaller than 40 makes no sense, so increase the initial value.

This fixes a regression introduced in 3.4 by commit:
e0c9a0219a
(my BCM4322 performance dropped from 18,4Mb/s to 9,26Mb/s)

675a0b049a mac80211: Use a cfg80211_chan_def in ieee80211_hw_conf_chan 
Drivers that don't use chanctxes cannot perform VHT association because
they still use a "backward compatibility" pair of {ieee80211_channel,
nl80211_channel_type} in ieee80211_conf and ieee80211_local.

3db1cd5c05 net: fix assignment of 0/1 to bool variables. 
DaveM said:
   Please, this kind of stuff rots forever and not using bool properly
   drives me crazy.

Joe Perches <joe@perches.com> gave me the spatch script:

	@@
	bool b;
	@@
	-b = 0
	+b = false
	@@
	bool b;
	@@
	-b = 1
	+b = true

I merely installed coccinelle, read the documentation and took credit.
