643a16a0eb misc: sgi-gru: fix use-after-free error in gru_set_context_option, gru_fault and gru_handle_user_call_os
In some bad situation, the gts may be freed gru_check_chiplet_assignment.
The call chain can be gru_unload_context->gru_free_gru_context->gts_drop
and kfree finally. However, the caller didn't know if the gts is freed
or not and use it afterwards. This will trigger a Use after Free bug.

Fix it by introducing a return value to see if it's in error path or not.
Free the gts in caller if gru_check_chiplet_assignment check failed.

fd2c930cf6 misc: tifm: fix possible memory leak in tifm_7xx1_switch_media()
If device_register() returns error in tifm_7xx1_switch_media(),
name of kobject which is allocated in dev_set_name() called in device_add()
is leaked.

Never directly free @dev after calling device_register(), even
if it returned an error! Always use put_device() to give up the
reference initialized.

1dbb4f0235 virt: acrn: Mark the uuid field as unused
After the commits for userspace (see Link tags below) the uuid field
is not being used in the ACRN code. Update kernel to reflect these
changes, i.e. do the following:
- adding a comment explaining that it's not used anymore
- replacing the specific type by a raw buffer
- updating the example code accordingly

The advertised field confused users and actually never been used.
So the wrong part here is that kernel puts something which userspace
never used and hence this may confuse a reader of this code.

Note, that there is only a single tool that had been prepared a year
ago for these forthcoming changes in the kernel.

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().

If device_register() returns error in ocxl_file_register_afu(),
the name allocated by dev_set_name() need be freed. As comment

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.

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.
