[ Upstream commit bdbbae241a04f387ba910b8609f95fad5f1470c7 ]

While any of the GPIO cdev syscalls is in progress, the kernel can call
gpiochip_remove() (for instance, when a USB GPIO expander is disconnected)
which will set gdev-&gt;chip to NULL after which any subsequent access will
cause a crash.

To avoid that: use an RW-semaphore in which the syscalls take it for
reading (so that we don't needlessly prohibit the user-space from calling
syscalls simultaneously) while gpiochip_remove() takes it for writing so
that it can only happen once all syscalls return.

Fixes: d7c51b47ac11 ("gpio: userspace ABI for reading/writing GPIO lines")

[ Upstream commit 533aae7c94dbc2b14301cfd68ae7e0e90f0c8438 ]

There are several places where we can crash the kernel by requesting
lines, unbinding the GPIO device, then calling any of the system calls
relevant to the GPIO character device's annonymous file descriptors:
ioctl(), read(), poll().

While I observed it with the GPIO simulator, it will also happen for any
of the GPIO devices that can be hot-unplugged - for instance any HID GPIO
expander (e.g. CP2112).

This affects both v1 and v2 uAPI.

This fixes it partially by checking if gdev-&gt;chip is not NULL but it
doesn't entirely remedy the situation as we still have a race condition
in which another thread can remove the device after the check.

Fixes: d7c51b47ac11 ("gpio: userspace ABI for reading/writing GPIO lines")
Fixes: 3c0d9c635ae2 ("gpiolib: cdev: support GPIO_V2_GET_LINE_IOCTL and GPIO_V2_LINE_GET_VALUES_IOCTL")

for_each_pci_dev() is implemented by pci_get_device(). The comment of
pci_get_device() says that it will increase the reference count for the
returned pci_dev and also decrease the reference count for the input
pci_dev @from if it is not NULL.

If we break for_each_pci_dev() loop with pdev not NULL, we need to call
pci_dev_put() to decrease the reference count. Add the missing
pci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULL
input parameter, there is no problem for the 'Device not found' branch.
For the normal path, add pci_dev_put() in amd_gpio_exit().

<title>gpiolib: fix memory leak in gpiochip_setup_dev()</title>

Here is a backtrace report about memory leak detected in
gpiochip_setup_dev():

unreferenced object 0xffff88810b406400 (size 512):
  comm "python3", pid 1682, jiffies 4295346908 (age 24.090s)
  backtrace:
    kmalloc_trace
    device_add		device_private_init at drivers/base/core.c:3361
			(inlined by) device_add at drivers/base/core.c:3411
    cdev_device_add
    gpiolib_cdev_register
    gpiochip_setup_dev
    gpiochip_add_data_with_key

gcdev_register() &amp; gcdev_unregister() would call device_add() &amp;
device_del() (no matter CONFIG_GPIO_CDEV is enabled or not) to
register/unregister device.

However, if device_add() succeeds, some resource (like
struct device_private allocated by device_private_init())
is not released by device_del().

Therefore, after device_add() succeeds by gcdev_register(), it
needs to call put_device() to release resource in the error handle
path.

Here we move forward the register of release function, and let it
release every piece of resource by put_device() instead of kfree().

While at it, fix another subtle issue, i.e. when gc-&gt;ngpio is equal
to 0, we still call kcalloc() and, in case of further error, kfree()
on the ZERO_PTR pointer, which is not NULL. It's not a bug per se,
but rather waste of the resources and potentially wrong expectation
about contents of the gdev-&gt;descs variable.

Update the driver to use an immutable IRQ chip to fix this warning:

    "not an immutable chip, please consider fixing it!"

Preserve per-chip labels by adding an -&gt;irq_print_chip() callback.

   - Provide a generic wrapper which can be utilized in drivers to

   - Fix up affected pinctrl and GPIO drivers to make them cleanly RT

  Interrupt drivers:

Pull pin control updates from Linus Walleij:
 "There is nothing exciting going on, no core changes, just a few
  drivers and cleanups.

  New drivers:

   - Cypress CY8C95x0 chip pin control support, along with an immediate
     cleanup

   - Mediatek MT8188 SoC pin control support

   - Qualcomm SM8450 and SC8280XP LPASS (low power audio subsystem) pin
     control support

   - Qualcomm PM7250, PM8450

   - Rockchip RV1126 SoC pin control support

  Improvements:

   - Fix some missing pins in the Armada 37xx driver

   - Convert Broadcom and Nomadik drivers to use PINCTRL_PINGROUP()
     macro

   - Fix some GPIO irq_chips to be immutable

   - Massive Qualcomm device tree binding cleanup, with more to come"

Pull more ACPI updates from Rafael Wysocki:
 "These fix two issues, in APEI and in the int3472 driver, clean up the
  ACPI thermal driver, add ACPI support for non-GPE system wakeup events
  and make the system reboot code use the S5 (system off) state by
  default.

  Specifics:

   - Fix ACPI device object reference counting in (recently updated)
     skl_int3472_fill_clk_pdata() (Andy Shevchenko).

   - Fix a memory leak in APEI by avoiding to add a task_work to kernel
     threads running when an asynchronous error is detected (Shuai Xue).

   - Add ACPI support for handling system wakeups via GPIO wake capable
     IRQs in addition to GPEs (Raul E Rangel).

   - Make the system reboot code put ACPI-enabled systems into the S5
     (system off) state which is necessary for some platforms to work as
     expected (Kai-Heng Feng).

   - Make the white space usage in the ACPI thermal driver more
     consistent and drop redundant code from it (Rafael Wysocki)"

* tag 'acpi-6.1-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  ACPI: thermal: Drop some redundant code
  ACPI: thermal: Drop redundant parens from expressions
  ACPI: thermal: Use white space more consistently
  platform/x86: int3472: Don't leak reference on error
  ACPI: APEI: do not add task_work to kernel thread to avoid memory leak
  PM: ACPI: reboot: Reinstate S5 for reboot
  kernel/reboot: Add SYS_OFF_MODE_RESTART_PREPARE mode
  ACPI: PM: Take wake IRQ into consideration when entering suspend-to-idle
  i2c: acpi: Use ACPI wake capability bit to set wake_irq
  ACPI: resources: Add wake_capable parameter to acpi_dev_irq_flags
  gpiolib: acpi: Add wake_capable variants of acpi_dev_gpio_irq_get
