The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The drivers uses a mutex and I2C bus access in its PMIC EIC chip
get implementation. This means these functions can sleep and the PMIC EIC
chip should set the can_sleep property to true.
This will ensure that a warning is printed when trying to get the
value from a context that potentially can't sleep.

As timbgpio_irq_enable()/timbgpio_irq_disable() callback could be
executed under irq context, it could introduce double locks on
&tgpio->lock if it preempts other execution units requiring
the same locks.
timbgpio_gpio_set()
--> timbgpio_update_bit()
--> spin_lock(&tgpio->lock)
<interrupt>
--> timbgpio_irq_disable()
--> spin_lock_irqsave(&tgpio->lock)
This flaw was found by an experimental static analysis tool I am
developing for irq-related deadlock.
To prevent the potential deadlock, the patch uses spin_lock_irqsave()
on &tgpio->lock inside timbgpio_gpio_set() to prevent the possible
deadlock scenario.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct linereq.
Additionally, since the element count member must be set before accessing
the annotated flexible array member, move its initialization earlier.

gpio_sim_make_line_names() returns NULL or ERR_PTR() so we must not use
__free(kfree) on the returned address. Split this function into two, one

one that actually sets the names at correct offsets. The allocation and

We access internals of struct gpio_device and struct gpio_desc because
it's easier but it can actually be avoided and we're working towards a
better encapsulation of GPIO data structures across the kernel so let's
start at home.
Instead of checking gpio_desc flags, let's just track the requests of
GPIOs in the driver. We also already store the information about
direction of simulated lines.
For kobjects needed by sysfs callbacks: we can iterate over the children
devices of the top-level platform device and compare their fwnodes
against the one passed to the init function from probe.
While at it: fix one line break and remove the untrue part about
configfs callbacks using dev_get_drvdata() from a comment.

git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86 into gpio/for-next
Immutable branch between pdx86 android tablets branch and GPIO due for the v6.7 merge window

On the Peaq C1010 2-in-1 INT33FC:00 pin 3 is connected to
a "dolby" button. At the ACPI level an _AEI event-handler
is connected which sets an ACPI variable to 1 on both
edges. This variable can be polled + cleared to 0 using WMI.
Since the variable is set on both edges the WMI interface is pretty
useless even when polling. So instead of writing a custom WMI
driver for this the x86-android-tablets code instantiates
a gpio-keys platform device for the "dolby" button.
Add an ignore_interrupt quirk for INT33FC:00 pin 3 on the Peaq C1010,
so that it is not seen as busy when the gpio-keys driver requests it.
Note this replaces a hack in x86-android-tablets where it would
call acpi_gpiochip_free_interrupts() on the INT33FC:00 GPIO
controller. acpi_gpiochip_free_interrupts() is considered private
(internal) gpiolib API so x86-android-tablets should stop using it.

In some cases where a broken AEI is present for a GPIO and the GPIO
is listed in the ignore_interrupt list to avoid the broken event
handler, the kernel may want to use the GPIO for another purpose.
Before this change trying to use such a GPIO for another purpose would
fail, because the ignore_interrupt list was only checked after
the acpi_request_own_gpiod() call, causing the GPIO to already be
claimed even though it is listed in the ignore_interrupt list.
Fix this by moving the ignore_interrupt list to above
the acpi_request_own_gpiod() call.

Calling gpiochip_find() from interrupt handler in this driver is an
abuse of the GPIO API. It only happens to work because nobody added a
might_sleep() to it and the lock used by GPIOLIB is a spinlock.
Both will soon be changed as we're limiting both the number of
interfaces allowed to be called from atomic context as well as making
struct gpio_chip private to the GPIO code that owns it. We'll also
switch to protecting the global GPIO device list with a mutex as there
is no reason to allow changes to it from interrupt handlers.
Instead of iterating over all SPRD chips and looking up each
corresponding GPIO chip, let's make each SPRD GPIO controller register
with a notifier chain. The chain will be called at interrupt so that
every chip that already probed will be notified. The rest of the
interrupt handling remains the same. This should result in faster code as
we're avoiding iterating over the list of all GPIO devices.

Associate the swnode of the GPIO device's (which is the interrupt
