Remove unnecessary blank line, and move close of multiple-line comments
to their own trailing lines. This fixes four checkpatch warnings and one
checkpatch check notice for the include/rtl8723b_hal.h file.

The to_usb_serial_port() macro is implemented using container_of() so
there's no need to check for NULL.
Note that neither bus match() or probe() is ever called with a NULL
struct device pointer so the checks weren't just misplaced.

All usb_serial drivers return 0 in their remove callbacks and driver
core ignores the value returned by usb_serial_device_remove(). So change
the remove callback to return void and return 0 unconditionally in
usb_serial_device_remove().

In a bus remove function the passed device is always valid, so there is
no need to check for it being NULL.
(Side note: The check for port being non-NULL is broken anyhow, because
to_usb_serial_port() is a wrapper around container_of() for a member that is
not the first one. So port can hardly become NULL.)

The usage of in_interrupt() in drivers is phased out for various
reasons.
In both exported functions where BUG_ON(in_interrupt()) is invoked,
there is a mutex_lock() afterwards. mutex_lock() contains a
might_sleep() which will already trigger a stack trace if the target
functions is called from atomic context.
Remove the BUG_ON() and add a "Context: " in the kernel-doc instead.

reset_vc() uses a "!in_interrupt()" conditional before resetting the
palettes, which is a blocking operation. Since commit
8b6312f4dcc1e ("[PATCH] vt: refactor console SAK processing")
all calls are invoked from a workqueue process context, with the
blocking console lock always acquired.
Remove the "!in_interrupt()" check.

Currently we use bitmap_alloc() to allocate msi bitmap which should be
initialized with zero. This is obviously wrong but it works because msi
can fallback to legacy interrupt mode. So use bitmap_zalloc() instead.

The dep->interval captures the number of frames/microframes per interval
from bInterval. Fullspeed interrupt endpoint bInterval is the number of
frames per interval and not 2^(bInterval - 1). So fix it here. This

endpoint operation.

Multiple structures in the carl9170 driver have alignment
impossible alignment constraints that gcc warns about when
building with 'make W=1':
drivers/net/wireless/ath/carl9170/fwcmd.h:243:2: warning: alignment 1 of 'union <anonymous>' is less than 4 [-Wpacked-not-aligned]
drivers/net/wireless/ath/carl9170/wlan.h:373:1: warning: alignment 1 of 'struct ar9170_rx_frame_single' is less than 2 [-Wpacked-not-aligned]
In the carl9170_cmd structure, multiple members that have an explicit
alignment requirement of four bytes are added into a union with explicit
byte alignment, but this in turn is part of a structure that also has
four-byte alignment.
In the wlan.h header, multiple structures contain a ieee80211_hdr member
that is required to be two-byte aligned to avoid alignmnet faults when
processing network headers, but all members are forced to be byte-aligned
using the __packed tag at the end of the struct definition.
In both cases, leaving out the packing does not change the internal
layout of the structure but changes the alignment constraint of the
structure itself.
Change all affected structures to only apply packing where it does
not violate the alignment requirement of the contained structure.

Consolidate the actions performed on the packet based on the XDP
program result into a separate function that is easier to read and
maintain. Simplify the i40e_construct_skb_zc function, so that the
input xdp buffer is always freed, regardless of whether the output
skb is successfully created or not. Simplify the behavior of the
i40e_clean_rx_irq_zc function, so that the current packet descriptor
is dropped when function i40_construct_skb_zc returns an error as
opposed to re-processing the same description on the next invocation.

For performance reasons, avoid writing the ring next-to-clean pointer

Instead, simply read it at initialization into a local copy, update

It is needed to test "offload failed" notifications.
Create the flag as part of nsim_fib_create() under fib directory and set
it to false by default.

"fail_route_offload" value is true, set the appropriate hardware flag to

If we vetoed the addition, we might get a delete or append notification
for a route we do not have. Therefore, do not warn if route was not found.

After installing a route to the kernel, user space receives an
acknowledgment, which means the route was installed in the kernel, but not
necessarily in hardware.
The asynchronous nature of route installation in hardware can lead to a
routing daemon advertising a route before it was actually installed in
hardware. This can result in packet loss or mis-routed packets until the
route is installed in hardware.
To avoid such cases, previous patch set added the ability to emit
RTM_NEWROUTE notifications whenever RTM_F_OFFLOAD/RTM_F_TRAP flags
are changed, this behavior is controlled by sysctl.
With the above mentioned behavior, it is possible to know from user-space
if the route was offloaded, but if the offload fails there is no indication
to user-space. Following a failure, a routing daemon will wait indefinitely
for a notification that will never come.
This patch adds an "offload_failed" indication to IPv6 routes, so that
users will have better visibility into the offload process.
'struct fib6_info' is extended with new field that indicates if route
offload failed. Note that the new field is added using unused bit and
therefore there is no need to increase struct size.

Currently if the driver is unable to get all the MSI-X vectors it wants, it
falls back to the minimum configuration which equates to a single Tx/Rx
traffic queue pair. Instead of using the minimum configuration, if given
more vectors than the minimum, utilize those vectors for additional traffic
queues after accounting for other interrupts.

The writeback enable logic was incorrectly implemented (due to
misunderstanding what the side effects of the implementation would be
during polling).
Fix this logic issue, while implementing a new feature allowing the user
to control the writeback frequency using the knobs for controlling
interrupt throttling that we already have. Basically if you leave
adaptive interrupts enabled, the writeback frequency will be varied even
if busy_polling or if napi-poll is in use. If the interrupt rates are
set to a fixed value by ethtool -C and adaptive is off, the driver will
allow the user-set interrupt rate to guide how frequently the hardware
will complete descriptors to the driver.
Effectively the user will get a control over the hardware efficiency,
allowing the choice between immediate interrupts or delayed up to a
maximum of the interrupt rate, even when interrupts are disabled
during polling.

The core clock frequency is currently hardcoded at 446 MHz for the RL
profile calculations. This causes issues since not all devices use that
clock frequency. Read the GLGEN_CLKSTAT_SRC register to determine which PSM
clock frequency is selected. This ensures that the rate limiter profile
calculations will be correct.

Create set scheduler aggregator node and move for VSIs into respective
scheduler node. Max children per aggregator node is 64.
There are two types of aggregator node(s) created.
1. dedicated node for PF and _CTRL VSIs
2. dedicated node(s) for VFs.
As part of reset and rebuild, aggregator nodes are recreated and VSIs
are moved to respective aggregator node.
Having related VSIs in respective tree avoid starvation between PF and VF
w.r.t Tx bandwidth.
