Ping-Ke Shih 8cf304a853 rtlwifi: btcoex: remove identical statements within if-else branches
Since the statements are identical, we can safely remove the statements.
The commit 42e74946f0 ("rtlwifi: btcoexist: Fix if == else warnings in
halbtc8821a1ant.c") had fixed the statements, but the commit c6821613e6
("rtlwifi: btcoex: follow linux coding style") that converted coding style
and upgraded btcoex didn't include the fix.

Siva Rebbagondla 78e450719c rsi: Fix 'invalid vdd' warning in mmc
While performing cleanup, driver is messing with card->ocr
value by not masking rocr against ocr_avail. Below panic
is observed with some of the SDIO host controllers due to
this. Issue is resolved by reverting incorrect modifications
to vdd.

The issue here is that we allocate "data" and then set
"data = PTR_ALIGN(data, 8);" and then we free the aligned pointer
instead of the original pointer.

kmalloc() pointers are already ARCH_SLAB_MINALIGN aligned which is 8 or
more on everything except certain Xtensa variants.  We decided that if
the Xtensa people ever notice a bug here then we'll tell them the bug is
on their side.  ;)

Ping-Ke Shih af8a41cccf rtlwifi: cleanup 8723be ant_sel definition
Some HP laptops have only a single wifi antenna. This would not be a
problem except that they were shipped with an incorrectly encoded
EFUSE. It should have been possible to open the computer and transfer
the antenna connection to the other terminal except that such action
might void the warranty, and moving the antenna broke the Windows
driver. The fix was to add a module option that would override the
EFUSE encoding. That was done with commit c18d8f5095 ("rtlwifi:
rtl8723be: Add antenna select module parameter"). There was still a
problem with Bluetooth coexistence, which was addressed with commit
baa1702290 ("rtlwifi: btcoexist: Implement antenna selection").
There were still problems, thus there were commit 0ff78adeef
("rtlwifi: rtl8723be: fix ant_sel code") and commit 6d62269283
("rtlwifi: btcoexist: Fix antenna selection code"). Despite all these
attempts at fixing the problem, the code is not yet right. A proper
fix is important as there are now instances of laptops having
RTL8723DE chips with the same problem.

The module parameter ant_sel is used to control antenna number and path.
At present enum ANT_{X2,X1} is used to define the antenna number, but
this choice is not intuitive, thus change to a new enum ANT_{MAIN,AUX}
to make it more readable. This change showed examples where incorrect
values were used. It was also possible to remove a workaround in
halbtcoutsrc.c.

The experimental results with single antenna connected to specific path
are now as follows:
  ant_sel  ANT_MAIN(#1)  ANT_AUX(#2)
     0        -8            -62
     1        -62           -10
     2        -6            -60

Luca Coelho a083429e13 iwlwifi: mvm: fix old scan version sizes
When version 8 of the scan command API was introduced, only the size
of version 7 was updated, causing older versions of the firmware to
throw BAD_COMMAND errors.

Calculating the old version based on the size of the latest version
got too complicated and the size of the older versions will never
change anyway, so it's better to just hardcoded the sizes.

Daniel Mack 4836ec42b0 wcn36xx: pass information elements in scan requests
When the wifi driver core passes IE elements in the scan request, append
them to the firmware message. The driver currently tells the core that
it is capable of attaching up to WCN36XX_MAX_SCAN_IE_LEN octets, but
doesn't actually pass them to the the hardware.

Note that this patch doesn't fix a bug that was observed. The change is
merely done for the sake of completeness as the hardware supports
appending IEs in scans. Tests show that network scans work fine with
this patch applied.

Some defines were moved around to avoid cyclic include dependencies.

This seems to be only interesting when scanning for a specific SSID

When the network interface goes down while a scan request is still
pending that can't be stopped due to firmware hickups, wcn->scan_req
remains set, even though the hardware is deinitialized. This results
in -EBUSY for all scan requests after the interface was brought up
again.

Fix this by explicitly completing pending scan requests in
wcn36xx_stop().

Daniel Mack 14ca3c98aa wcn36xx: abort scan request when 'dequeued' indicator is sent
When the firmware sends a WCN36XX_HAL_SCAN_IND_DEQUEUED indication,
the request is apparently no longer valid. Attempts to stop the hardware
scan request subsequently will lead to the following error message, and
the hardware is no longer able to communicate with any AP:

[   57.917186] wcn36xx: ERROR hal_stop_scan_offload response failed err=5

Interpreting this indicator message as scan abortion fixes this.

While at it, add a newline to a debug print.

Govind Singh 4945af5b26 ath10k: enable SRRI/DRRI support on ddr for WCN3990
SRRI/DRRI are not mapped in the HW Shadow block and can lead
to un-clocked access if common subsystem in the target is
powered down due to idle mode.

To mitigate this problem SRRI/DRRI can be read from
DDR instead of doing an actual hardware read.
Host allocates non cached memory on ddr and configures
the physical address of this memory to the CE hardware.
The hardware updates the RRI on this particular location.
Read SRRI/DRRI from DDR location instead of
direct target read.

Enable retention restore on ddr using hw params to enable
in specific targets.

Rakesh Pillai 20529b33aa ath10k: enable hw checksum for wcn3990
By default ath10k driver enables the support for HW_CHECKSUM
(NETIF_F_HW_CSUM). Since the TCP/UDP checksum calculation is not enabled
in the wcn3990 firmware the checksum is incorrect in the TCP/UDP packets
and all patckets are dropped. But due note that wcn3990 support in
ath10k is still incomplete so this isn't a critical fix (yet).

Enable hw checksum calculations in wcn3990 hardware by

Daniel Mack 0fc8bb50bb wcn36xx: pass correct BSS index when deleting BSS keys
The firmware message to delete BSS keys expects a BSS index to be passed.
This field is currently hard-coded to 0. Fix this by passing in the index
we received from the firmware when the BSS was configured.

The encryption type in that message also needs to be set to what was used
when the key was set, so the assignment of vif_priv->encrypt_type is now
done after the firmware command was sent. This reportedly fixes the
following error in AP mode:

  wcn36xx: ERROR hal_remove_bsskey response failed err=6

Also, AFAIU, when a BSS is deleted, the firmware apparently drops all the
keys associated with it. Trying to remove the key explicitly afterwards
will hence lead to the following message:

  wcn36xx: ERROR hal_remove_bsskey response failed err=16

This is now suppressed with an extra check for the BSS index validity.

Wen Gong fa3440fa2f ath10k: convert wow pattern from 802.3 to 802.11
When trying to set wow wakeup patterns it fails with this command:

iw phyxx wowlan enable patterns offset xx+ IP address xx.xx.xx.xx

The reason is that the wow pattern from upper layer is in 802.3 format
for this case, it need to convert it to 802.11 format. The input
offset parameter is used for 802.3, but the actual offset firmware
need depends on rx_decap_mode, so that it needs to be recalculated.
Pattern of 802.3 packet is not same with 802.11 packet. If the
rx_decap_mode is ATH10K_HW_TXRX_NATIVE_WIFI, then firmware will
receive data packet with 802.11 format from hardware.

Tested with QCA6174 hw3.0 with firmware
WLAN.RM.4.4.1-00099-QCARMSWPZ-1, but this will also affect QCA9377.
This has always failed, so it's not a regression with new firmware
