4a50d45450 cw1200: Fix a signedness bug in cw1200_load_firmware()
The "priv->hw_type" is an enum and in this context GCC will treat it
as an unsigned int so the error handling will never trigger.

Fixes: a910e4a94f69 ("cw1200: add driver for the ST-E CW1100 & CW1200 WLAN chipsets")

bcde60e599 rtw88: remove misleading module parameter rtw_fw_support_lps
The module parameter rtw_fw_support_lps is misleading. It
is not used to represent the firmware's property, but to
determine if driver wants to ask firmware to enter LPS.

However, driver should better enable/disable PS through
cfg80211_ops::set_power_mgmt instead.
For example, one could use iw command to set PS state.

  $ sudo iw wlanX set power_save [on/off]

So rtw_fw_support_lps should be removed because it is
misleading and useless. Instead of checking the parameter,
set PS mode according to IEEE80211_CONF_PS.

04b786e009 rtw88: add deep PS PG mode for 8822c
Compare with LCLK mode, PG mode saves more power, by turning
off more circuits. Therefore, to recover from PG mode, driver
needs to backup some information into rsvd page. Such as CAM
entries, DPK results.

As CAM entries can change, it is required to re-download CAM
entries after set_key.

d3be4d115b rtw88: select deep PS mode when module is inserted
Add a module parameter to select deep PS mode. And the mode
cannot be changed after the module has been inserted and probed.
If anyone wants to change the deep mode, should change the mode
and probe the device again to setup the changed deep mode.

When the device is probed, driver will check the deep PS mode
with different IC's PS mode suppotability. If none of the
PS mode is matched, the deep PS mode is changed to NONE,
means deep PS is disabled.

27e117e4b0 rtw88: add deep power save support
Deep power save allows firmware/hardware to operate in a
lower power state. And the deep power save mode depends on
LPS mode. So, before entering deep PS, driver must first
enter LPS mode.

Under Deep PS, most of hardware functions are shutdown,
driver will not be able to read/write registers and transfer
data to the device. Hence TX path must be protected by each
interface. Take PCI for example, DMA engine should be idle,
and no nore activities on the PCI bus.

If driver wants to operate on the device, such as register
read/write, it must first acquire the mutex lock and wake
up from Deep PS, otherwise the behavior is undefined.

37ba5de2e7 rtw88: leave PS state for dynamic mechanism
Dynamic mechanism requires BB/RF working to adjust
hardware settings. But PS state periodically turns
off BB/RF, could lead to wrong setting.

So leave PS state before DM to make sure it works.
And then check if we can enter PS state again.

3d391c06d9 rtw88: not to control LPS by each vif
The original design of LPS enter/leave routines allows
to control the LPS state by each interface. But the
hardware cannot actually handle it that way. This means
the hardware can only enter LPS once with an associated
port, so there is no need to keep tracking the state of
each vif.

Hence the logic of enter/leave LPS state can be simple,
just to check the state of the device's flag. And for
leaving LPS state, it will get the same port id to send
to inform the hardware.

61d7309562 rtw88: not to enter or leave PS under IRQ
Remove PS related *_irqsafe functions to avoid entering/leaving PS
under interrupt context. Instead, make PS decision in watch_dog.
This could simplify the logic and make the code look clean.

But it could have a little side-effect that if the driver is having
heavy traffic before the every-2-second watch_dog detect the traffic
and decide to leave PS, the thoughput will be lower. Once traffic is
detected by watch_dog and left PS state, the throughput will resume
to the peak the hardware ought to have again.

6f0b0d28fd rtw88: pci: reset H2C queue indexes in a single write
If the driver doesn't reset the host's and device's indexes
in a single write, the indexes will become different in a
short period. And it will confuse the DMA engine, make it
start to process non-existed entries.

Better to Write-1-to-reset the indexes, for the DMA engine
to know that this is a reset of the H2C queue, not a kick
off.

ab8c31dd8c net/wireless: Use kmemdup rather than duplicating its implementation
kmemdup is introduced to duplicate a region of memory in a neat way.
Rather than kmalloc/kzalloc + memcpy, which the programmer needs to
write the size twice (sometimes lead to mistakes), kmemdup improves
readability, leads to smaller code and also reduce the chances of mistakes.
Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy.

306547608c ath10k: switch to ieee80211_tx_dequeue_ni
Since ath10k_mac_tx_push_txq() can be called from process context, we
must explicitly disable softirqs before the call into mac80211.

By calling ieee80211_tx_dequeue_ni() instead of ieee80211_tx_dequeue()
we make sure softirqs are always disabled even in the case when
ath10k_mac_tx_push_txq() is called from process context.

Calling ieee80211_tx_dequeue_ni() with softirq's already disabled
(e.g., from softirq context) should be safe as the local_bh_disable()
and local_bh_enable() functions (called from ieee80211_tx_dequeue_ni)
are fully reentrant.

e0ae4bac22 brcmfmac: fix suspend/resume when power is cut off
brcmfmac assumed the wifi device always remains powered on and thus
hardcoded the MMC_PM_KEEP_POWER flag expecting the wifi device to
remain on even during suspend/resume cycles.

This is not always the case, some appliances cut power to everything
connected via SDIO for efficiency reasons and this leads to wifi not
being usable after coming out of suspend because the device was not
correctly reinitialized.

So we check for the keep_power capability and if it's not present then
we remove the device and probe it again during resume to mirror what's
happening in hardware and ensure correct reinitialization in the case
when MMC_PM_KEEP_POWER is not supported.
