The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

On the ASUS laptop UX325JA/UX425JA, most of the media keys are not
working due to the ASUS WMI driver fails to be loaded. The ACPI error
as follows leads to the failure of asus_wmi_evaluate_method.
ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [IIA3] at bit offset/length 96/32 exceeds size of target Buffer (96 bits) (20200326/dsopcode-203)
No Local Variables are initialized for Method [WMNB]
ACPI Error: Aborting method \_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20200326/psparse-531)
The DSDT for the WMNB part shows that 5 DWORD required for local
variables and the 3rd variable IIA3 hit the buffer limit.
Method (WMNB, 3, Serialized)
{ ..
CreateDWordField (Arg2, Zero, IIA0)
CreateDWordField (Arg2, 0x04, IIA1)
CreateDWordField (Arg2, 0x08, IIA2)
CreateDWordField (Arg2, 0x0C, IIA3)
CreateDWordField (Arg2, 0x10, IIA4)
Local0 = (Arg1 & 0xFFFFFFFF)
If ((Local0 == 0x54494E49))
..
}
The limitation is determined by the input acpi_buffer size passed
to the wmi_evaluate_method. Since the struct bios_args is the data
structure used as input buffer by default for all ASUS WMI calls,
the size needs to be expanded to fix the problem.

chasis-type
The HP Stream x360 11-p000nd no longer report SW_TABLET_MODE state / events
with recent kernels. This model reports a chassis-type of 10 / "Notebook"
which is not on the recently introduced chassis-type whitelist
Commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a chassis-type whitelist and only listed 31 /
"Convertible" as being capable of generating valid SW_TABLET_MOD events.
Commit 1fac39fd0316 ("platform/x86: intel-vbtn: Also handle tablet-mode
switch on "Detachable" and "Portable" chassis-types") extended the
whitelist with chassis-types 8 / "Portable" and 32 / "Detachable".
And now we need to exten the whitelist again with 10 / "Notebook"...
The issue original fixed by the whitelist is really a ACPI DSDT bug on
the Dell XPS 9360 where it has a VGBS which reports it is in tablet mode
even though it is not a 2-in-1 at all, but a regular laptop.
So since this is a workaround for a DSDT issue on that specific model,
instead of extending the whitelist over and over again, lets switch to
a blacklist and only blacklist the chassis-type of the model for which
the chassis-type check was added.
Note this also fixes the current version of the code no longer checking
if dmi_get_system_info(DMI_CHASSIS_TYPE) returns NULL.

pm_runtime_get_sync() increments the runtime PM usage counter even

This commit:
818e915fbac5: ("irqchip: Add Loongson HyperTransport Vector support")
Added a MIPS-only driver, but turned on compilation on all other architectures as well:
config LOONGSON_HTVEC
bool "Loongson3 HyperTransport Interrupt Vector Controller"
depends on MACH_LOONGSON64 || COMPILE_TEST
But this driver was never build tested on any other architecture than MIPS:
drivers/irqchip/irq-loongson-htvec.c: In function ‘htvec_irq_dispatch’:
drivers/irqchip/irq-loongson-htvec.c:59:3: error: implicit declaration of function ‘spurious_interrupt’; did you mean ‘smp_reboot_interrupt’? [-Werror=implicit-function-declaration]
Because spurious_interrupt() only exists on MIPS.

This introduces mtdpstore, which is similar to mtdoops but more
powerful. It uses pstore/blk, and aims to store panic and oops logs to
a flash partition, where pstore can later read back and present as files
in the mounted pstore filesystem.
To make mtdpstore work, the "blkdev" of pstore/blk should be set
as MTD device name or MTD device number. For more details, see
Documentation/admin-guide/pstore-blk.rst
This solves a number of issues:
- Work duplication: both of pstore and mtdoops do the same job storing
panic/oops log. They have very similar logic, registering to kmsg
dumper and storing logs to several chunks one by one.
- Layer violations: drivers should provides methods instead of polices.
MTD should provide read/write/erase operations, and allow a higher
level drivers to provide the chunk management, kmsg dump
configuration, etc.
- Missing features: pstore provides many additional features, including
presenting the logs as files, logging dump time and count, and
supporting other frontends like pmsg, console, etc.

The mlx5 Kconfig conflict is a case where we just take the

the ESWITCH dependency by one level of indirection which is
what the 'net' conflicting change is trying to ensure.

Currently when a VSI is built (i.e. reset, set channels, etc.)
the coalesce settings will be preserved in most cases. However, when the
number of q_vectors are increased the settings for the new q_vectors
will be set to the driver defaults of AIM on, Rx/Tx ITR 50, and INTRL 0.
This is causing issues with how the ethtool layer gets the current
coalesce settings since it only uses q_vector 0. So, assume that the user
set the coalesce settings globally (i.e. ethtool -C eth0) and use q_vector
0's settings for all of the new q_vectors.

A VF driver has the ability to request reset via VIRTCHNL_OP_RESET_VF.
This is a required step in VF driver load. Currently, the PF is only
allowing a VF to request reset using this method after the VF has
already communicated resources via VIRTCHNL_OP_GET_VF_RESOURCES.
However, this is incorrect because the VF can request reset before
requesting resources. Fix this by allowing the VF to request a reset

Currently the PF is modifying the VF's port VLAN on the fly when
configured via iproute. This is okay for most cases, but if the VF
already has guest VLANs configured the PF has to remove all of those
filters so only VLAN tagged traffic that matches the port VLAN will
pass. Instead of adding functionality to track which guest VLANs have
been added, just reset the VF each time port VLAN parameters are
modified.

Currently a user is not allowed to clear a VF's administratively set MAC
on the PF. Fix this by allowing an all zero MAC address via "ip link set
${pf_eth} vf ${vf_id} mac 00:00:00:00:00:00".
An example use case for this would be issuing a "virsh shutdown"
command on a VM. The call to iproute mentioned above is part of this flow.
Without this change the driver incorrectly rejects clearing the VF's
administratively set MAC and prints unhelpful log messages.
Also, improve the comments surrounding this change.

NAND ECC modes (or providers) have their own enumeration but, unlike
their algorithms counterpart, there is no invalid or uninitialized
value to discriminate between an error and having chosen a no-ECC
situation. Add an "invalid" entry for this purpose.

There is an enumeration to list ECC algorithm, let's use it instead of
returning an int.

This scheme has been introduced for the Davinci controller and means
that the OOB area must be read *before* the rest of the data. This has
nothing to do with the ECC in OOB placement as it could be understood
and most importantly, there is no point in having this function out of
the Davinci NAND controller driver. A DT property for this scheme has
been added but never used, even by the Davinci driver which only uses
this scheme to change the default nand_read_page().
Move the main read_page() helper into the Davinci driver and remove
the remaining boilerplate.

In new code, the use of typedef is discouraged. Turn this one in the
raw NAND core into a regular enumeration.

This helper is not very useful and very often people get confused:
they use nand_release() instead of nand_cleanup().
Now that all drivers have been converted to do not use nand_release()
anymore, let's remove this helper.

The remaining operation to do from this goto statement is to cleanup
