ACPI: sysfs: validate return type of _STR method

commit 4bb1e7d027413835b086aed35bc3f0713bc0f72b upstream.

Only buffer objects are valid return values of _STR.

If something else is returned description_show() will access invalid
memory.

ACPI: sysfs: Fix create_pnp_modalias() and create_of_modalias()

ACPI: sysfs: Fix create_pnp_modalias() and create_of_modalias()

[ Upstream commit 48cf49d31994ff97b33c4044e618560ec84d35fb ]

snprintf() does not return negative values on error.

To know if the buffer was too small, the returned value needs to be
compared with the length of the passed buffer. If it is greater or
equal, the output has been truncated, so add checks for the truncation
to create_pnp_modalias() and create_of_modalias(). Also make them
return -ENOMEM in that case, as they already do that elsewhere.

Moreover, the remaining size of the buffer used by snprintf() needs to
be updated after the first write to avoid out-of-bounds access as
already done correctly in create_pnp_modalias(), but not in
create_of_modalias(), so change the latter accordingly.

Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.3-rc1.

There's a lot of changes this development cycle, most of the work
falls into two different categories:

- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.

- driver core changes to work to make struct bus_type able to be
moved into read-only memory (i.e. const) The recent work with Rust
has pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only
making things safer overall. This is the contuation of that work
(started last release with kobject changes) in moving struct
bus_type to be constant. We didn't quite make it for this release,
but the remaining patches will be finished up for the release after
this one, but the groundwork has been laid for this effort.

Other than that we have in here:

- debugfs memory leak fixes in some subsystems

- error path cleanups and fixes for some never-able-to-be-hit
codepaths.

- cacheinfo rework and fixes

- Other tiny fixes, full details are in the shortlog

All of these have been in linux-next for a while with no reported
problems"

that there's a pending report that has a fix that is queued up - Linus ]

Pull ACPI updates from Rafael Wysocki:
"These fix a frequency limit issue in the ACPI processor performance
library code, fix a few issues in the ACPICA code, improve Crystal
Cove support in the ACPI PMIC driver, fix string handling in the ACPI
battery driver, add IRQ override quirks for a few machines more, fix
other assorted problems and clean up code and documentation.

Specifics:

- Drop port I/O validation for some regions to avoid AML failures due
to rejections of legitimate port I/O writes (Mario Limonciello)

- Constify acpi_get_handle() pathname argument to allow its callers
to pass const pathnames to it (Sakari Ailus)

- Fix typo in CDAT DSMAS struct definition (Lukas Wunner)

- Drop an unnecessary (void *) conversion from the ACPI processor
driver (Zhou jie)

- Modify the ACPI processor performance library code to use the "no
limit" frequency QoS as appropriate and adjust the intel_pstate
driver accordingly (Rafael Wysocki)

- Add support for NBFT to the ACPI table parser (Stuart Hayes)

- Introduce list of known non-PNP devices to avoid enumerating some
of them as PNP devices (Rafael Wysocki)

- Add x86 ACPI paths to the ACPI entry in MAINTAINERS to allow
scripts to report the actual maintainers information (Rafael
Wysocki)

- Add two more entries to the ACPI IRQ override quirk list (Adam
Niederer, Werner Sembach)

- Add a pmic_i2c_address entry for Intel Bay Trail Crystal Cove to
allow intel_soc_pmic_exec_mipi_pmic_seq_element() to be used with
the Bay Trail Crystal Cove PMIC OpRegion driver (Hans de Goede)

- Add comments with DSDT power OpRegion field names to the ACPI PMIC
driver (Hans de Goede)

- Fix string termination handling in the ACPI battery driver (Armin
Wolf)

- Limit error type to 32-bit width in the ACPI APEI error injection
code (Shuai Xue)
