27158c7267 ocxl: fix pci device refcount leak when calling get_function_0()
get_function_0() calls pci_get_domain_bus_and_slot(), as comment
says, it returns a pci device with refcount increment, so after
using it, pci_dev_put() needs be called.

Get the device reference when get_function_0() is not called, so
pci_dev_put() can be called in the error path and callers
unconditionally. And add comment above get_dvsec_vendor0() to tell
callers to call pci_dev_put().

a4cb1004ae misc: ocxl: fix possible name leak in ocxl_file_register_afu()
If device_register() returns error in ocxl_file_register_afu(),
the name allocated by dev_set_name() need be freed. As comment
of device_register() says, it should use put_device() to give
up the reference in the error path. So fix this by calling
put_device(), then the name can be freed in kobject_cleanup(),
and info is freed in info_release().

72b8ec15f9 accessibility: speakup: phonetic spelling while arrowing letter by letter
This patch includes an enhancement requested frequently on the mailing
list.[1][2] It adds a variable, cur_phonetic in the spk_vars, which can
be set as a module parameter, as well as in /sys/speakup/cur_phonetic.
This patch also documents cur_phonetic as a sysfs attribute in
sysfs-driver-speakup.

When cur_phonetic=1, it causes speakup to speak letters phonetically if
paused on the character while arrowing through a word.

When a user does not set cur_phonetic to any value, the default value
for it would be 0.

Slimbus core interrupt is getting fired after suspend. At this point
ADSP slimbus hardware is off with gated clocks which is leading to an
unclocked access when HLOS slimbus tried to read the interrupt
status register in the ISR.

27dfc44e1b dt-bindings: nvmem: Introduce the nvmem-layout container
The nvmem devices description works like this:

* Most cases (EEPROM & co):

eeprom@x {
	 compatible = "<eeprom-compatible>";
	 ...
};

* MTD case:

flash@y {
	compatible = "<flash-compatible>";
	...
	otp {
		compatible = "user-otp"; /* or "factory-otp" */
		...
	};
};

In the former case, the nvmem device is "eeprom@x", while in the latter
case the nvmem device is "otp".

Nvmem devices can produce nvmem cells. The current way to describe nvmem
cells is to locate them by providing their static byte and bit offset
and length. These information are stored in subnodes of the nvmem
device.

It is now a fact that such description does not fit more advanced use
cases where the location or the size of the cells may vary. There are
currently three known situations which require being described
differently: Kontron's SL28 VPD, ONIE's TLV table and U-Boot's
environment variables.

Hence, we need a way to describe the parsers that must be used in order
to make the dynamic discovery of the nvmem cells. This new description
must fit both use cases (the generic situation and the MTD case).

Let's create in both cases a container node named nvmem-layout whose
content will depend on the parser. Right now nvmem-layout.yaml is
"empty", but references to additional layout parser bindings will be
inserted in the near future. The final goal being something that looks
like:

* Most cases (EEPROM & co):

eeprom@x {
	compatible = "<eeprom-compatible>";
	...
	nvmem-layout {
		compatible = "<parser-compatible>";
		...
	};
};

* MTD case:

flash@y {
	compatible = "<flash-compatible>";
	...
	otp {
		compatible = "user-otp"; /* or "factory-otp" */
		...
		nvmem-layout {
			compatible = "<parser-compatible>";
			...
		};
	};
};

42b868b032 dt-bindings: nvmem: Fix example
Despite not being listed nor required within the top level nvmem yaml
file, the "compatible" property is mandatory and is actually enforced by
all the nvmem provider bindings.

Unfortunately, the lack of compatible in the nvmem.yaml to level
description file lead to the example not matching anything and thus not
being checked at all.

Let's pick a compatible almost randomly (one which is already used with
the qfprom label) to make the example at least valid on a semantic
point of view and getting it checked.

For a second modification of this word, these ECC become invalid and
this OTP will be no more accessible, the shadowed value is invalid.

This patch adds a warning to indicate an upper OTP update, because this
operation is dangerous as OTP is not locked by the driver after the first
update to avoid a second update.

e6278a5445 virtio_console: Introduce an ID allocator for virtual console numbers
When a virtio console port is initialized, it is registered as an hvc
console using a virtual console number. If a KVM guest is started with
multiple virtio console devices, the same vtermno (or virtual console
number) can be used to allocate different hvc consoles, which leads to
various communication problems later on.

This is also reported in debugfs :

  # grep vtermno /sys/kernel/debug/virtio-ports/*
  /sys/kernel/debug/virtio-ports/vport1p1:console_vtermno: 1
  /sys/kernel/debug/virtio-ports/vport2p1:console_vtermno: 1
  /sys/kernel/debug/virtio-ports/vport3p1:console_vtermno: 2
  /sys/kernel/debug/virtio-ports/vport4p1:console_vtermno: 3

Replace the next_vtermno global with an ID allocator and start the
allocation at 1 as it is today. Also recycle IDs when a console port
is removed.

83f47eea74 mei: add timeout to send
When driver wakes up the firmware from the low power state,
it is sending a memory ready message.
The send is done via synchronous/blocking function to ensure
that firmware is in ready state. However, in case of firmware
undergoing reset send might be block forever.
To address this issue a timeout is added to blocking
write command on the internal bus.

Introduce the __mei_cl_send_timeout function to use instead of
__mei_cl_send in cases where timeout is required.
The mei_cl_write has only two callers and there is no need to split
it into two functions.
