With sizeof(), it is preferable to use the variable of type <type> instead
of sizeof(<type>).
There are multiple places where a temporary variable is used to hold a
'size' value which is then used for a subsequent alloc/memset. Get rid
of the temporary variable by calculating size as part of the alloc/memset
statement.
Also remove unnecessary type-cast.

VSI supported nodes are calculated in order to add the VSI parent or
intermediate nodes to the scheduler tree. If one of the node in below
layers (from VSI layer) has space to add the new VSI or intermediate node
above that layer then it's not required to continue the calculation further
for below layers.

Currently ICE_MAX_MTU subtracts only ETH_HLEN from max frame size and
adds ETH_FCS_LEN and VLAN_HLEN, which is not what was intended.
The ETH_HLEN + ETH_FCS_LEN + VLAN_HLEN expression should be surrounded
with parentheses.
Wrap mentioned expression and take into account VLAN double tagging.

Commit 87b0984ebfab ("net: Add extack argument to ndo_fdb_add()") in
net-next added an extended parameter to the .ndo_fdb_add op and changed
ice_fdb_add() accordingly. Update the function header and add the
__always_unused attribute to the new parameter to avoid -Wunused-parameter
warnings.

I have encountered an interrupt storm during the eMMC chip probing (and
the chip finally didn't get detected). It turned out that U-Boot left
the DMAC interrupts enabled while the Linux driver didn't use those.
The SDHI driver's interrupt handler somehow assumes that, even if an
SDIO interrupt didn't happen, it should return IRQ_HANDLED. I think
that if none of the enabled interrupts happened and got handled, we
should return IRQ_NONE -- that way the kernel IRQ code recoginizes
a spurious interrupt and masks it off pretty quickly...

The only user of mmc_align_data_size() is sdio_align_size(), which is
called from SDIO func drivers to let them distinguish, how to optimally
allocate data buffers.
Let's move mmc_align_data_size() close to the SDIO code as to make it
static, rename it to _sdio_align_size() and simplify its definition, all
with the purpose of clarifying that this is SDIO specific.

ME FW contributes a vital role in HDCP2.2 authentication.
HDCP2.2 driver needs to communicate to ME FW for each step of the
HDCP2.2 authentication.
ME FW prepare and HDCP2.2 authentication parameters and encrypt them
as per spec. With such parameter Driver prepares HDCP2.2 auth messages
and communicate with HDCP2.2 sink.
Similarly HDCP2.2 sink's response is shared with ME FW for decrypt and
verification.
Once All the steps of HDCP2.2 authentications are complete on driver's
request ME FW will configure the port as authenticated and supply the
HDCP keys to the Gen HW for encryption.
Only after this stage HDCP2.2 driver can start the HDCP2.2 encryption
for a port.
ME FW is interfaced to kernel through MEI Bus Driver. To obtain the
HDCP2.2 services from the ME FW through MEI Bus driver MEI Client
Driver is developed.

I set 10 seconds for the timeout of the i915 audio component binding
with a hope that recent machines are fast enough to handle all probe
tasks in that period, but I was too optimistic. The binding may take
longer than that, and this caused a problem on the machine with both
audio and graphics driver modules loaded in parallel, as Paul Menzel
experienced. This problem haven't hit so often just because the KMS
driver is loaded in initrd on most machines.
As a simple workaround, extend the timeout to 60 seconds.

When using the mmc_spi driver with a card-detect pin, I noticed that the
card was not detected immediately after probe, but only after it was
unplugged and plugged back in (and the CD IRQ fired).
The call tree looks something like this:
mmc_spi_probe
mmc_add_host
mmc_start_host
_mmc_detect_change
mmc_schedule_delayed_work(&host->detect, 0)
mmc_rescan
host->bus_ops->detect(host)
mmc_detect
_mmc_detect_card_removed
host->ops->get_cd(host)
mmc_gpio_get_cd -> -ENOSYS (ctx->cd_gpio not set)
mmc_gpiod_request_cd
ctx->cd_gpio = desc
To fix this issue, call mmc_detect_change after the card-detect GPIO/IRQ
is registered.

MMC OF parsing functions, which parses various host DT properties, should
stay close to each other. Therefore, let's move mmc_of_parse_voltage()
close to mmc_of_parse() into host.c.
Additionally, there is no reason to build the code only when CONFIG_OF is
set, as there should be stub functions for the OF helpers that is being
used, so let's drop this condition as well.

The mmc regulator helper functions, are placed in the extensive core.c
file. In a step towards trying to create a better structure of files,
avoiding too many lines of code per file, let's move these helpers to a new
file, regulator.c.
Moreover, this within this context it makes sense to also drop the export
of mmc_vddrange_to_ocrmask(), but instead let's make it internal to the mmc
core.

There is a messy cast here:
min_t(int, len, (int)sizeof(*item)));
min_t() should normally cast to unsigned. It's not possible for "len"
to be negative, but if it were then we definitely wouldn't want to pass
negatives to read_extent_buffer(). Also there is an extra cast.
This patch shouldn't affect runtime, it's just a clean up.

At ctree.c:key_search(), the assertion that verifies the first key on a
child extent buffer corresponds to the key at a specific slot in the
parent has a disadvantage: we effectively hit a BUG_ON() which requires
rebooting the machine later. It also does not tell any information about
which extent buffer is affected, from which root, the expected and found
keys, etc.
However as of commit 581c1760415c48 ("btrfs: Validate child tree block's
level and first key"), that assertion is not needed since at the time we
read an extent buffer from disk we validate that its first key matches the
key, at the respective slot, in the parent extent buffer. Therefore just
remove the assertion at key_search().

The function map_private_extent_buffer() can return an -EINVAL error, and
it is called by generic_bin_search() which will return back the error. The
btrfs_bin_search() function in turn calls generic_bin_search() and the
key_search() function calls btrfs_bin_search(), so both can return the
-EINVAL error coming from the map_private_extent_buffer() function. Some
callers of these functions were ignoring that these functions can return
an error, so fix them to deal with error return values.

The lock needs to be released, it's there to protect access to the

invalid value so the default: branch is taken.

We recently had a customer issue with a corrupted filesystem. When
trying to mount this image btrfs panicked with a division by zero in
calc_stripe_length().
The corrupt chunk had a 'num_stripes' value of 1. calc_stripe_length()
takes this value and divides it by the number of copies the RAID profile
is expected to have to calculate the amount of data stripes. As a DUP
profile is expected to have 2 copies this division resulted in 1/2 = 0.
Later then the 'data_stripes' variable is used as a divisor in the
stripe length calculation which results in a division by 0 and thus a
kernel panic.
When encountering a filesystem with a DUP block group and a
'num_stripes' value unequal to 2, refuse mounting as the image is
corrupted and will lead to unexpected behaviour.
Code inspection showed a RAID1 block group has the same issues.

Comparing the content of the pages in the range to deduplicate is now
done in generic_remap_checks called by the generic helper
generic_remap_file_range_prep(), which takes care of ensuring we do not
compare/deduplicate undefined data beyond a file's EOF (range from EOF
to the next block boundary). So remove these checks which are now
redundant.
