ad5f411b7f rtw88: 8821c: add set tx power index
To configure the transmit power of 8821c implement trasmit
power index setting callback function for 8821c. This is very
similar to the callback function of 8822b.

cce0e08301 wilc1000: let wilc_mac_xmit() return NETDEV_TX_OK
The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type defining 'NETDEV_TX_OK' but this
driver returns '0' instead of 'NETDEV_TX_OK'.

Fix this by returning 'NETDEV_TX_OK' instead of '0'.

b424808115 brcm80211: brcmsmac: Move LEDs to GPIO descriptors
The code in the BRCM80211 BRCMSMAC driver is using the legacy
GPIO API to to a complex check of the validity of the base of
the GPIO chip and whether it is present at all and then adding
an offset to the base of the chip.

Use the existing function to obtain a GPIO line internally
from a GPIO chip so we can use the offset directly and
modernize the code to use GPIO descriptors instead of integers
from the global GPIO numberspace.

29e354ebee brcmfmac: Transform compatible string for FW loading
The driver relies on the compatible string from DT to determine which
FW configuration file it should load. The DTS spec allows for '/' as
part of the compatible string. We change this to '-' so that we will
still be able to load the config file, even when the compatible has a
'/'. This fixes explicitly the firmware loading for
"solidrun,cubox-i/q".

2fa8085fc6 brcmfmac: set pacing shift before transmitting skb to bus
Linux 3.6 introduces TSQ which has a per socket threshold for TCP Tx
packet to reduce latency. In flow control mode, host driver enqueues skb
in hanger and TCP doesn't push new skb frees until host frees the skb when
receiving fwstatus event. So set pacing shift 8 to send them as a single
large aggregate frame to the bus layer.

fcdd7a875d brcmfmac: set state of hanger slot to FREE when flushing PSQ
When USB or SDIO device got abnormal bus disconnection, host driver
tried to clean up the skbs in PSQ and TXQ (The skb's pointer in hanger
slot linked to PSQ and TSQ), so we should set the state of skb hanger slot
to BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb.
In brcmf_fws_bus_txq_cleanup it already sets
BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb, therefore we add the
same thing in brcmf_fws_psq_flush to avoid following warning message.

there is no sdiod rx credit available for control path causing host

card. So in order to prevent it some credits are reserved for control
path.

Note that TXCTL_CREDITS can't be larger than the firmware default
credit update threshold 2; otherwise there will be a deadlock for both

WILC1000 is an IEEE 802.11 b/g/n IoT link controller module. The
WILC1000 connects to Microchip AVR/SMART MCUs, SMART MPUs, and other
processors with minimal resource requirements with a simple
SPI/SDIO-to-Wi-Fi interface.

WILC1000 driver has been part of staging for few years. With
contributions from the community, it has improved significantly. Full
driver review has helped in achieving the current state.

01e34233c6 ath11k: fix wmi peer flags in peer assoc command
Currently need ptk/gtk wmi peer flags in wmi peer assoc cmd
are set based on the rsnie and wpaie of the bss from the bss list.
Since this bss list is not updated with current BSSID for AP mode,
we may not find bss from the bss list. Which results in ptk/gtk peer
flags are not set in the wmi peer assoc cmd. Due to this EAPOL frames
are going in data rates instead of management rates.

preparation for adding analagous support in the LSM for set*gid()
syscalls, we add the requisite hook here. Tested by putting print

during kernel boot.

55e20bd12a Revert "btrfs: switch to iomap_dio_rw() for dio"
This reverts commit a43a67a2d7.

This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.

The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.

Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.

There have been discussions how to fix that, but revert seems to be the
least intrusive option.

bc139119a1 net: ethernet: ti: ale: fix allmulti for nu type ale
On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
unregistered mcast packets to pass.

This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit 9d1f644727 ("net: ethernet: ti: ale: fix
seeing unreg mcast packets with promisc and allmulti disabled").

Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().

3e1ad4054b doc: don't use deprecated "---help---" markers in target docs
I'm not convinced the script makes useful automaed help lines anyway,
but since we're trying to deprecate the use of "---help---" in Kconfig
files, let's fix the doc example code too.

See commit a7f7f6248d ("treewide: replace '---help---' in Kconfig
files with 'help'")
