netdev_lock is already held when calling bnxt_ulp_irq_stop() and
bnxt_ulp_irq_restart(). When converting rtnl_lock to netdev_lock,
the original code was rtnl_dereference() to indicate that rtnl_lock
was already held. rcu_dereference_protected() is the correct
conversion after replacing rtnl_lock with netdev_lock.
Add a new helper netdev_lock_dereference() similar to
rtnl_dereference().

After UFS_ABORT_TASK has been processed successfully, the host will
generate MCQ IRQ for ABORT TAG with response OCS_ABORTED. This results in
ufshcd_compl_one_cqe() calling ufshcd_release_scsi_cmd().
But ufshcd_mcq_abort() already calls ufshcd_release_scsi_cmd(), resulting
in __ufshcd_release() being called twice. This means
hba->clk_gating.active_reqs will be decreased twice, making it go
negative.
Delete ufshcd_release_scsi_cmd() in ufshcd_mcq_abort().

While the MDIO address of the internal PHY on Allwinner sun8i chips is
generally 1, of_mdio_parse_addr is used to cleanly parse the address
from the device-tree instead of hardcoding it.
A commit reworking the code ditched the parsed value and hardcoded the
value 1 instead, which didn't really break anything but is more fragile
and not future-proof.
Restore the initial behavior using the parsed address returned from the
helper.

Cover three recent cases:
1. missing ops locking for the lowers during netdev_sync_lower_features
2. missing locking for dev_set_promiscuity (plus netdev_ops_assert_locked
with a comment on why/when it's needed)
3. rcu lock during team_change_rx_flags
Verified that each one triggers when the respective fix is reverted.
Not sure about the placement, but since it all relies on teaming,
added to the teaming directory.
One ugly bit is that I add NETIF_F_LRO to netdevsim; there is no way
to trigger netdev_sync_lower_features without it.

The current implementation of per-pdev frequency range updates assumes that
each pdev supports only a single band. As a result in ath12k_regd_update(),
bands are handled using an if-else structure, which limits updates to only
one of the band per pdev. This assumption does not hold for all chipsets.
For example, the WCN7850 supports multiple bands within a single pdev.
Hence to accommodate such cases, update the logic to account for all band
cases by handling each band in a separate if conditions instead of the
previous if-else structure.

Commit 3ef9f710efcb ("pinctrl: mediatek: Add EINT support for multiple
addresses") introduced an access to the 'soc' field of struct
mtk_pinctrl in mtk_eint_do_init() and for that an include of
pinctrl-mtk-common-v2.h.
However, pinctrl drivers relying on the v1 common driver include
pinctrl-mtk-common.h instead, which provides another definition of
struct mtk_pinctrl that does not contain an 'soc' field.
Since mtk_eint_do_init() can be called both by v1 and v2 drivers, it
will now try to dereference an invalid pointer when called on v1
platforms. This has been observed on Genio 350 EVK (MT8365), which
crashes very early in boot (the kernel trace can only be seen with
earlycon).
In order to fix this, since 'struct mtk_pinctrl' was only needed to get
a 'struct mtk_eint_pin', make 'struct mtk_eint_pin' a parameter
of mtk_eint_do_init() so that callers need to supply it, removing
mtk_eint_do_init()'s dependency on any particular 'struct mtk_pinctrl'.

On Qualcomm platforms if the board uses GPIO hogs msm_pinmux_request()
calls gpiochip_line_is_valid(). After commit 8015443e24e7 ("gpio: Hide
valid_mask from direct assignments") gpiochip_line_is_valid() uses
gc->gpiodev, which is NULL when GPIO hog pins are being processed.
Thus after this commit using GPIO hogs causes the following crash. In
order to fix this, verify that gc->gpiodev is not NULL.
Note: it is not possible to reorder calls (e.g. by calling
msm_gpio_init() before pinctrl registration or by splitting
pinctrl_register() into _and_init() and pinctrl_enable() and calling the
latter function after msm_gpio_init()) because GPIO chip registration
would fail with EPROBE_DEFER if pinctrl is not enabled at the time of
registration.

Going bus-off on a channel doing RX could result in dropped packets.
As netif_running() gets cleared before the channel abort procedure,
the handling of any last RDATA packets would see netif_rx() return
non-zero to signal a dropped packet. kvaser_pciefd_read_buffer() dealt
with this "error" by breaking out of processing the remaining DMA RX
buffer.
Only return an error from kvaser_pciefd_read_buffer() due to packet
corruption, otherwise handle it internally.

The functions kvaser_pciefd_start_xmit() and
kvaser_pciefd_handle_ack_packet() raced to stop/wake TX queues and
get/put echo skbs, as kvaser_pciefd_can->echo_lock was only ever taken
when transmitting and KCAN_TX_NR_PACKETS_CURRENT gets decremented
prior to handling of ACKs. E.g., this caused the following error:
can_put_echo_skb: BUG! echo_skb 5 is occupied!
Instead, use the synchronization helpers in netdev_queues.h. As those
piggyback on BQL barriers, start updating in-flight packets and bytes
counts as well.

Avoid the driver missing IRQs by temporarily masking IRQs in the ISR
to enforce an edge even if a different IRQ is signalled before handled
IRQs are cleared.

The ti_k3_dsp_remoteproc.c driver asserts the local reset in probe
and releases the module reset in .prepare callback. This is done to
ensure the core does not execute bogus code when module reset is
deasserted.
Put both of these operations together in .prepare callback, which is
more suitable as it ensures local reset is asserted for subsequent core
start operations from sysfs. This is done to align the .prepare callback
of DSP with the M4 driver which can be factored out at a later stage.

Currently, the driver overrides the rproc ops when booting in IPC-only
mode. Remove these overrides and register the ops unconditionally. This
requires to have IPC-only mode checks in the .prepare and .unprepare ops
and returning early. The other rproc ops are invoked when booting either
in IPC-only mode or in remoteproc mode but not both.
This is done to align the rproc ops implementations of DSP driver with
M4 driver and can be factored out at a later stage.
