Sujith Manoharan 69bdacc8fb ath9k_hw: Fix thermal issue with UB94
Hardcode the output voltage of x-PA bias LDO to the lowest
value for UB94. The card doesn't get too hot now.

Felix Fietkau df3c8b2b10 ath9k_hw: remove antenna configuration eeprom ops and variables
AR9280 based hardware with 3 antennas and slow antenna diversity has
not been seen in the wild and ath9k does not support that form of
antenna diversity, so remove the EEPROM ops for it.
These EEPROM ops are currently only used for setting the
AR_PHY_SWITCH_COM register, which is being done in the EEPROM specific
file already.

Matteo Croce 841051602e ath9k: fix bug in tx power

The resulting value is assigned in an u16 which overflows and makes

Felix Fietkau 601e0cb165 ath9k_hw: fix antenna diversity on AR9285
On AR9285, the antenna switch configuration register uses more than just
16 bits. Because of an arbitrary mask applied to the EEPROM value that
stores this configuration, diversity was broken in some cases, leading
to a significant degradation in signal strength.
Fix this by changing the callback to return a 32 bit value and remove
the arbitrary mask.

Joe Perches a4b770972b drivers/net: Remove unnecessary returns from void function()s
This patch removes from drivers/net/ all the unnecessary
return; statements that precede the last closing brace of
void functions.

It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.

It also does not remove null void functions with return.

Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
  xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

Luis R. Rodriguez 49101676b2 ath9k_hw: restore mac address reading logic
Once upon a time the AR_EEPROM_MAC macro was added to let us
add a random attribute to the three 4-bytes of MAC addresses
entries we read from the EEPROM. This was good while a random
high-enough value was used which did not conflict with any
of the already existing enum eeprom_param values. With AR9003
support the enums overlap and it means we either increment
the random offset or just restore the reading logic to match
what the HAL has. I choose to do the later to synchronize
the logic on both code bases.

This should fix reading the MAC address from the EEPROM
on AR9003 hardware.

We split PHY stuff up first for the AR5008 and AR9002
