Felix Fietkau de40f316c0 ath9k_hw: extend ath9k_hw_set_txpowerlimit to test channel txpower
ath9k_hw_set_txpowerlimit gets an extra boolean parameter that - if set -
causes the rate txpower table and the regulatory limit to be calculated
and stored, without changing hardware registers.

Arnd Bergmann 6038f373a3 llseek: automatically add .llseek fop
All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.

The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.

New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time.  Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.

The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.

Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.

Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

// This adds an llseek= method to all file operations,
// as a preparation for making no_llseek the default.
//
// The rules are
// - use no_llseek explicitly if we do nonseekable_open
// - use seq_lseek for sequential files
// - use default_llseek if we know we access f_pos
// - use noop_llseek if we know we don't access f_pos,
//   but we still want to allow users to call lseek

Some APs advertise that they may be HT40 capable in the capabilites
but the current operating channel configuration may be only HT20.
This causes disconnection as ath9k_htc sets WLAN_RC_40_FLAG despite
the AP operating in HT20 mode.
Hence set this flag only if the current channel configuration
is HT40 enabled.

Felix Fietkau 20bd2a0952 ath9k_hw: clean up per-channel calibration data
The noise floor history buffer is currently not kept per channel, which
can lead to problems when changing channels from a clean channel to a
noisy one. Also when switching from HT20 to HT40, the noise floor
history buffer is full of measurements, but none of them contain data
for the extension channel, which it needs quite a bit of time to recover
from.

This patch puts all the per-channel calibration data into a single data
structure, and gives the the driver control over whether that is used
per-channel or even not used for some channels.

For ath9k_htc, I decided to keep this per-channel in order to avoid
creating regressions.

For ath9k, the data is kept only for the operating channel, which saves
some space. ath9k_hw takes care of wiping old data when the operating
channel or its channel flags change.

Sujith 881ac6a535 ath9k_htc: Revamp CONF_IDLE handling
This patch revamps IDLE power save handling in the driver.
Two separate functions (radio enable/disable) are introduced,
because the semantics of radio handling is just not the same
as the start()/stop() callbacks. For example, the HW must not
be disabled, instead, the PHY has to be disabled in radio_disable().
Also, the HW has to be reset properly in radio enable/disable and
certain registers have to be programmed only once, in the
start() callback.

The radio_enable() routine doesn't need the PS wrappers since
we set the HW power mode to AWAKE anyway before calling it.

Dan Carpenter 0730d11419 ath9k/htc_drv_main: off by one error
I changed "> ATH9K_HTC_MAX_TID" to ">= ATH9K_HTC_MAX_TID" to avoid a
potential overflow.

This is a stray null dereference.  We initialize "ista" properly later on.

Sujith 2ff6575b1e ath9k_htc: Handle IDLE LED properly
Switch LED off/on when handling CONF_CHANGE_IDLE.
Not doing this would leave the radio LED on even
though the chip would be in full sleep mode.

Sujith 9c6dda4e2d ath9k_htc: Fix beaconing in IBSS mode
The current way of managing beaconing in ad-hoc
mode has a subtle race - the beacon obtained from mac80211
is freed in the SWBA handler rather than the TX
completion routine. But transmission of beacons goes
through the normal SKB queue maintained in hif_usb,
leading to a situation where __skb_dequeue() in the TX
completion handler goes kaput.

Fix this by simply getting a beacon from mac80211 for
every SWBA and free it in its completion routine.

were exposed by sparse. It's a miracle that the driver
worked at all till now.
