8ce9beac46 drivers: net: wireless: b43: Fix possible NULL ptr dereference
On the ternary expression the 'e' variable could be NULL dereferenced,
when b43_nphy_get_rf_ctl_over_rev7 function returns NULL.

0c201cfbfd b43: N-PHY: don't use deprecated b43_radio_foo16
All radio ops are 16b (there is only 1 exception for reg 0x1), so we
deprecated b43_radio_read16 and b43_radio_write16 long time ago.

b43: N-PHY: implement spurious tone avoidance
This commit made BCM4322 use only MCS 0 on channel 13, which of course
resulted in performance drop (down to 0.7Mb/s).

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)
