Joe Perches 2c208890c6 wireless: Remove casts to same type
Adding casts of objects to the same type is unnecessary
and confusing for a human reader.

For example, this cast:

        int y;
        int *p = (int *)&y;

I used the coccinelle script below to find and remove these
unnecessary casts.  I manually removed the conversions this
script produces of casts with __force, __iomem and __user.

@@
type T;
T *p;
@@

-       (T *)p
+       p

Neatened the mwifiex_deauthenticate_infra function which
was doing odd things with array pointers and not using
is_zero_ether_addr.

Gabor Juhos 21bd6ea311 ath9k: use consistent value for REDUCE_SCALED_POWER_BY_THREE_CHAIN
The REDUCE_SCALED_POWER_BY_THREE_CHAIN symbol is
defined in different eeprom files, and the value
varies between the different files.

In eeprom_def.c and in ar9003_eeprom.c the value
of the symbol is 9, however the comments in these
files indicates the value should be 10*log10(3)*2
which is 9.54242509439325. Replace the the value
to 10 in these files.

Also add comments to eeprom_9287.c.

Rajkumar Manoharan a261f0e965 ath9k_hw: Fix minimum CTL power for each runtime mode
The conformance test limits (CTL) for each regulatory domains
(FCC/ETSI/MKK) are programmed for each runtime modes (11B,11G,
HT20 and HT40) in EEPROM. The lowest ctledge power value of a
particular running mode should not be used while computing
ctledge power for a different running mode.(i.e 11G's min ctledge
power should not be used while computing ctledge power for HT20).

Currently, the code does not handle this properly which would
result in incorrect txpowers in certain cases. So reset the
twiceMaxEdgePower to the default while computing min ctlegepower
for every mode.

Felix Fietkau ca2c68cc7b ath9k_hw: clean up tx power handling
The code for handling various restrictions concerning regulatory limits,
antenna gain, etc. is very convoluted and duplicated across various
EEPROM parsing implementations, making it hard to review.

This patch partially cleans up the mess by unifying regulatory limit
handling in one function and simplifying handling of antenna gain.
It also removes unused transmit power scaling arrays from the EEPROM code,
which belonged to an unimplemented API that isn't supposed to be in
the driver anyway.

Rajkumar Manoharan e7fc63388d ath9k_hw: Speedup register ops for HTC driver
Fine-tuning register write operation and avoid unnecessay
delays for ath9k_htc driver, saves hw reset time which
improves scanning time and also solves one of the following
scenario.

Sometimes the ACK is sent by STA for assoc response is not
seen at AP side. So the AP continues to send retry assoc
responses. At the STA side, since the assoc response was
already forwarded to mac80211, it proceeded to channel change
which in turns does chip reset.

In most of the cases the chip reset was completed before
max retries are reached at AP side. Hence STA can able to ACK
the retried frames again. But in clear environment these retries
are completed within shortspan of time.

Since ath9k_htc consumes more time for hw reset, this latency
is causing dissociation by AP due to max reties are reached.
This issue was originally reported with Cisco Aironet 1250 AP
in HT40 mode in noise free environment.

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; }'

with some cleanups by hand.

Compile tested x86 allmodconfig only.

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.

Luis R. Rodriguez 8fe6536850 ath9k_hw: Move some RF ops to the private callbacks
The PHY split is easier done in a few steps. First move
the RF ops to the private ops and rename them accordingly.
We split PHY stuff up first for the AR5008 and AR9002
families. There are some callbacks that AR9002 share
with the AR5008 familiy so we set those first, if AR9002
has some different callbacks it will override them upon
hardware init.

Senthil Balasubramanian e41f0bfcb1 ath9k: Fix bugs in handling TX power
* Get power table offset from the EEPROM instead of using
  a hardcoded value of -5 if the EEPROM rev is >= 21.
* Add support in the 4k eeprom code for tx power offset
  in case we have a 4k AR9280 implementation.
* Fix tx power accuracy at high powers.

ath9k uses this for now, ath9k_htc is expected to re-use this
as well. We lave ath5k as is, but it certainly can also be
converted later.

The ath9k module parameter and debugfs entry is kept.

DPRINTF() is used in hw specific related code, as such
ensure we don't rely on the private driver core ath_softc
struct when calling it. Drivers can then implement their
own DPRINTF() as they see fit.
