platform/x86: acer-wmi: Fix missing capability check
During the rework of the fan behavior control code in commit
d8e8362b09 ("platform/x86: acer-wmi: Fix setting of fan behavior"),
acer_toggle_turbo() was changed to use WMID_gaming_set_fan_behavior()
instead of WMID_gaming_set_u64() when switching the fans to turbo
mode. The new function however does not check if the necessary
capability (ACER_CAP_TURBO_FAN) is actually enabled on a given
machine, causing the driver to potentially access unsupported
features.

Fix this by manually checking if ACER_CAP_TURBO_FAN is enabled
on a given machine before changing the fan mode.

platform/x86: hp-bioscfg: Fix automatic module loading
hp-bioscfg has a MODULE_DEVICE_TABLE with a GUID in it that looks
plausible, but the module doesn't automatically load on applicable
systems.

This is because the GUID has some lower case characters and so it
doesn't match the modalias during boot. Update the GUIDs to be all
uppercase.

platform/x86: hp-bioscfg: Fix kernel panic in GET_INSTANCE_ID macro
The GET_INSTANCE_ID macro that caused a kernel panic when accessing sysfs
attributes:

1. Off-by-one error: The loop condition used '<=' instead of '<',
   causing access beyond array bounds. Since array indices are 0-based
   and go from 0 to instances_count-1, the loop should use '<'.

2. Missing NULL check: The code dereferenced attr_name_kobj->name
   without checking if attr_name_kobj was NULL, causing a null pointer
   dereference in min_length_show() and other attribute show functions.

The panic occurred when fwupd tried to read BIOS configuration attributes:

  Oops: general protection fault [#1] SMP KASAN NOPTI
  KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]
  RIP: 0010:min_length_show+0xcf/0x1d0 [hp_bioscfg]

Add a NULL check for attr_name_kobj before dereferencing and corrects
the loop boundary to match the pattern used elsewhere in the driver.

platform/x86: hp-bioscfg: Fix kobject warnings for empty attribute names
The hp-bioscfg driver attempts to register kobjects with empty names when
the HP BIOS returns attributes with empty name strings. This causes
multiple kernel warnings:

  kobject: (00000000135fb5e6): attempted to be registered with empty name!
  WARNING: CPU: 14 PID: 3336 at lib/kobject.c:219 kobject_add_internal+0x2eb/0x310

Add validation in hp_init_bios_buffer_attribute() to check if the
attribute name is empty after parsing it from the WMI buffer. If empty,
log a debug message and skip registration of that attribute, allowing the
module to continue processing other valid attributes.

platform/x86: hp-bioscfg: Fix out-of-bounds array access in ACPI package parsing
The hp_populate_*_elements_from_package() functions in the hp-bioscfg
driver contain out-of-bounds array access vulnerabilities.

These functions parse ACPI packages into internal data structures using
a for loop with index variable 'elem' that iterates through
enum_obj/integer_obj/order_obj/password_obj/string_obj arrays.

When processing multi-element fields like PREREQUISITES and
ENUM_POSSIBLE_VALUES, these functions read multiple consecutive array
elements using expressions like 'enum_obj[elem + reqs]' and
'enum_obj[elem + pos_values]' within nested loops.

The bug is that the bounds check only validated elem, but did not consider
the additional offset when accessing elem + reqs or elem + pos_values.

The fix changes the bounds check to validate the actual accessed index.

platform/x86: ibm_rtl: fix EBDA signature search pointer arithmetic
The ibm_rtl_init() function searches for the signature but has a pointer
arithmetic error. The loop counter suggests searching at 4-byte intervals
but the implementation only advances by 1 byte per iteration.

Fix by properly advancing the pointer by sizeof(unsigned int) bytes
each iteration.

Here is the big set of staging driver updates for 6.19-rc1.  Only thing
 "major" in here is that two subsystems, gpib and vc04 have moved out of
 the staging tree into the "real" portion of the kernel, which is great
 to see.  Other than that, the rest of the changes are just tiny coding
 style cleanups, nothing earth-shattering.
 
 All of these have been in linux-next for a while with no reported

500920fa76 gpio updates for v6.19-rc1
GPIO core:
 - add proper support for shared GPIOs that's aiming to replace the
   current sharing mechanism (which provides no synchronization ot enable
   counting) and enable it for Qualcomm platforms
 - improve the software node GPIO lookup by using the fwnode
   representation instead of the software node's name which was prone to
   bugs (GPIO controllers don't have to use the software node's name as
   their kernel label)
 - remove the last user of legacy-of-mm-gpiochip.h and drop the header
 - move closer to removing the legacy gpio_request_one() routine
 - rename some symbols for consistency
 - shrink GPIO printk() helpers by reusing existing code
 - remove some redundant kernel messages
 - use min() instead of min_t() in GPIO ACPI code
 - use system_percpu_wq instead of system_wq in GPIO character device code
 
 New drivers:
 - add a driver for the QIXIS FPGA GPIO controller
 
 Driver improvements:
 - use modernized variants of power management macros across a wide array
   of drivers in order to avoid having to use the __maybe_unused attribute
 - convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
   instead of the platform bus as they are not really described in
   firmware
 - use lock guards and update symbol prefixes in gpio-mmio
 - support the bryx radio interface kit in gpio-mpsse + refactor the
   driver
 - use software nodes for configuring the reset-gpio driver, including
   setting up the reference to the shared "reset" pin
 - check and propagate the return value of gpiod_set_value() to user-space
   in gpio-virtuser (this was previously not possible as this function
   returned void)
 - extend the gpio-regmap helper with more features (bypass cache for
   aliased inputs, force writes for aliased data registers, add a new
   configuration parameter)
 - remove unneeded includes from gpio-aspeed and gpio-latch
 - add support for Tegra410 to gpio-tegra186
 - replace PCI-specific PM with generic device-level PM in gpio-bt8xx
 - use dynamic GPIO range allocation in gpio-loongson-64bit
 - improve handling of level-triggered interrupts in gpio-pca953x
 - add suspend/resume support to gpio-fxl6408
 - add support for more models to gpio-menz127
 - optimize gpio-mvebu interrupt handling by avoiding unnecessary calls
   to mvebu_gpio_irq_handler()
 - make locking more consistent in gpio-grgpio
 
 Device-tree bindings:
 - document new NXP and Microchip models
 
 Documentation:
 - add a comprehensive compatibility and feature list for gpio-pca953x,
   which is a great addition as it's probably the most commonly used GPIO
   expander driver
 - kernel-doc tweaks
 
 Late fixes:
 - use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson

Merge tag 'gpio-updates-for-v6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "There's one new driver, lots of various updates to existing ones, some
  refactoring support for new models and misc tweaks and fixes.

  The biggest new feature in GPIO core is adding support for managed,
  enable-counted sharing of GPIO pins, something that - until now - was
  only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag
  which basically allowed drivers to "fight it out" for the descriptor
  and provided no synchronization. It was enabled on Qualcomm platforms
  (and thus is enabled on arm64 defconfig) and I plan on removing
  GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to
  the new mechanism.

  GPIO core:
   - add proper support for shared GPIOs that's aiming to replace the
     current sharing mechanism (which provides no synchronization ot
     enable counting) and enable it for Qualcomm platforms
   - improve the software node GPIO lookup by using the fwnode
     representation instead of the software node's name which was prone
