43951585e1 xattr.h: Replace zero-length array with flexible-array member
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]

This issue was found with the help of Coccinelle.

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]

de05842076 tipc: Fix potential tipc_node refcnt leak in tipc_rcv
tipc_rcv() invokes tipc_node_find() twice, which returns a reference of
the specified tipc_node object to "n" with increased refcnt.

When tipc_rcv() returns or a new object is assigned to "n", the original
local reference of "n" becomes invalid, so the refcount should be
decreased to keep refcount balanced.

The issue happens in some paths of tipc_rcv(), which forget to decrease
the refcnt increased by tipc_node_find() and will cause a refcnt leak.

Fix this issue by calling tipc_node_put() before the original object
pointed by "n" becomes invalid.

441870ee42 tipc: Fix potential tipc_aead refcnt leak in tipc_crypto_rcv
tipc_crypto_rcv() invokes tipc_aead_get(), which returns a reference of
the tipc_aead object to "aead" with increased refcnt.

When tipc_crypto_rcv() returns, the original local reference of "aead"
becomes invalid, so the refcount should be decreased to keep refcount
balanced.

The issue happens in one error path of tipc_crypto_rcv(). When TIPC
message decryption status is EINPROGRESS or EBUSY, the function forgets
to decrease the refcnt increased by tipc_aead_get() and causes a refcnt
leak.

Fix this issue by calling tipc_aead_put() on the error path when TIPC
message decryption status is EINPROGRESS or EBUSY.

nr_add_node() invokes nr_neigh_get_dev(), which returns a local
reference of the nr_neigh object to "nr_neigh" with increased refcnt.

When nr_add_node() returns, "nr_neigh" becomes invalid, so the refcount
should be decreased to keep refcount balanced.

The issue happens in one normal path of nr_add_node(), which forgets to
decrease the refcnt increased by nr_neigh_get_dev() and causes a refcnt
leak. It should decrease the refcnt before the function returns like
other normal paths do.

Fix this issue by calling nr_neigh_put() before the nr_add_node()
returns.

67791202c5 ALSA: hda/realtek - Fix unexpected init_amp override
The commit 1c76aa5fb4 ("ALSA: hda/realtek - Allow skipping
spec->init_amp detection") changed the way to assign spec->init_amp
field that specifies the way to initialize the amp.  Along with the
change, the commit also replaced a few fixups that set spec->init_amp
in HDA_FIXUP_ACT_PROBE with HDA_FIXUP_ACT_PRE_PROBE.  This was rather
aligning to the other fixups, and not supposed to change the actual
behavior.

However, this change turned out to cause a regression on FSC S7020,
which hit exactly the above.  The reason was that there is still one
place that overrides spec->init_amp after HDA_FIXUP_ACT_PRE_PROBE
call, namely in alc_ssid_check().

This patch fixes the regression by adding the proper spec->init_amp
override check, i.e. verifying whether it's still ALC_INIT_UNDEFINED.

c843b382e6 hwmon: (jc42) Fix name to have no illegal characters
The jc42 driver passes I2C client's name as hwmon device name. In case
of device tree probed devices this ends up being part of the compatible
string, "jc-42.4-temp". This name contains hyphens and the hwmon core
doesn't like this:

jc42 2-0018: hwmon: 'jc-42.4-temp' is not a valid name attribute, please fix

This changes the name to "jc42" which doesn't have any illegal
characters.

c90f3b8c4b clang-format: don't indent namespaces
This change doesn't affect existing code. Inner namespace indentation
can lead to a lot of indentation in the case of anonymous namespaces and
the like, impeding readability. Of the clang-format builtin styles
LLVM, Google, Chromium and Mozilla use None while WebKit uses Inner.

48fd5b5ee7 x86/split_lock: Bits in IA32_CORE_CAPABILITIES are not architectural
The Intel Software Developers' Manual erroneously listed bit 5 of the
IA32_CORE_CAPABILITIES register as an architectural feature. It is not.

Features enumerated by IA32_CORE_CAPABILITIES are model specific and
implementation details may vary in different cpu models. Thus it is only
safe to trust features after checking the CPU model.

Icelake client and server models are known to implement the split lock
detect feature even though they don't enumerate IA32_CORE_CAPABILITIES

[ tglx: Use switch() for readability and massage comments ]

c4b4c2a78a buffer: remove useless comment and WB_REASON_FREE_MORE_MEM, reason.
free_more_memory func has been completely removed in commit bc48f001de
("buffer: eliminate the need to call free_more_memory() in __getblk_slow()")

So comment and `WB_REASON_FREE_MORE_MEM` reason about free_more_memory
are no longer needed.
