carl9170: Fix wrong completion usage
carl9170_usb_stop() is used from several places to flush and cleanup any
pending work. The normal pattern is to send a request and wait for the
irq handler to call complete(). The completion is not reinitialized
during normal operation and as the old comment indicates it is important
to keep calls to wait_for_completion_timeout() and complete() balanced.
Calling complete_all() brings this equilibirum out of balance and needs
to be fixed by a reinit_completion(). But that opens a small race
window. It is possible that the sequence of complete_all(),
reinit_completion() is faster than the wait_for_completion_timeout() can
do its work. The wake up is not lost but the done counter test is after
reinit_completion() has been executed. The only reason we don't see
carl9170_exec_cmd() hang forever is we use the timeout version of
wait_for_copletion().
Let's fix this by reinitializing the completion (that is just setting
done counter to 0) just before we send out an request. Now,
carl9170_usb_stop() can be sure a complete() call is enough to make
progess since there is only one waiter at max. This is a common pattern
also seen in various drivers which use completion.

ath6kl: Allow the radio to report 0 dbm txpower without timing out
The ath6kl driver attempts to get the txpower value from the radio by first
clearing the existing stored value and then watching the value to become
non-zero.
APs allow setting client power to values from -127..127, but this radio
is not capable of setting values less then 0 and so will report txpower
as 0dbm for both negative and 0 client power values.
When the radio has txpower set to 0dbm txpower (equivalent to 1mw) the
ath6kl_cfg80211_get_txpower() function will remain in the
wait_event_interruptible_timeout() loop waiting for the value to be
non-zero, and will eventually timeout. This results in a 5 second delay in
response. However, the correct value of zero is eventually returned.
The 6004 defaults to 63dbm which is then limited by regulatory and
hardware limits with max of 18dbm (6003 max is 16dbm), therefore we can
use values larger then these to be able to determine when the value has
been updated.
To correct the issue, set the value to a nonsensical value (255) and wait
for it to change to the valid value.
Tested on both 6003 and 6004 based radios. Return value of zero is
correctly returned in an expected amount of time (similar to when
returning non-zero values) when AP client power is set to both 0 and
negative values.

While increasing number of clients, the average throughput drops

Processing txqs for every tx completion is causing overhead. Ideally for
management frame tx completion, pending txqs processing can be avoided.

add basic register-field manipulation macros
Common approach to accessing register fields is to define
structures or sets of macros containing mask and shift pair.
Operations on the register are then performed as follows:
field = (reg >> shift) & mask;
reg &= ~(mask << shift);
reg |= (field & mask) << shift;
Defining shift and mask separately is tedious. Ivo van Doorn
came up with an idea of computing them at compilation time
based on a single shifted mask (later refined by Felix) which
can be used like this:
#define REG_FIELD 0x000ff000
field = FIELD_GET(REG_FIELD, reg);
reg &= ~REG_FIELD;
reg |= FIELD_PREP(REG_FIELD, field);
FIELD_{GET,PREP} macros take care of finding out what the
appropriate shift is based on compilation time ffs operation.
GENMASK can be used to define registers (which is usually
less error-prone and easier to match with datasheets).
This approach is the most convenient I've seen so to limit code
multiplication let's move the macros to a global header file.
Attempts to use static inlines instead of macros failed due
to false positive triggering of BUILD_BUG_ON()s, especially with
GCC < 6.0.

ath9k: bring back direction setting in ath9k_{start_stop}
A regression was introduced in commit id
79d4db1214a ("ath9k: cleanup
led_pin initial") that broken the WLAN status led on my laptop with
AR9287 after suspending and resuming.
Steps to reproduce:
* Suspend (laptop)
* Resume (laptop)
* Observe that the WLAN led no longer turns ON/OFF depending on the
status and is always red
Even though for my case it only needs to be set to OUT in ath9k_start
but for consistency bring back the IN direction setting as well.

brcmfmac: fix pmksa->bssid usage
The struct cfg80211_pmksa defines its bssid field as:
const u8 *bssid;
contrary to struct brcmf_pmksa, which uses:
u8 bssid[ETH_ALEN];
Therefore in brcmf_cfg80211_del_pmksa(), &pmksa->bssid takes the address
of this field (of type u8**), not the one of its content (which would be
u8*). Remove the & operator to make brcmf_dbg("%pM") and memcmp()
behave as expected.
This bug have been found using a custom static checker (which checks the
usage of %p... attributes at build time). It has been introduced in
commit
6c404f34f2bd ("brcmfmac: Cleanup pmksa cache handling code"),
which replaced pmksa->bssid by &pmksa->bssid while refactoring the code,
without modifying struct cfg80211_pmksa definition.
Replace &pmk[i].bssid with pmk[i].bssid too to make the code clearer,
this change does not affect the semantic.

Commit
97f2645f358b ("tree-wide: replace config_enabled() with

This is one of the postponed TODO items as config_enabled() is used
for a tristate option here. Theoretically, config_enabled() is
equivalent to IS_BUILTIN(), but I guess IS_REACHABLE() is the best
fit for this case because both CONFIG_HWMON and CONFIG_ATH10K are
tristate.
