The Kconfig for this file is:
drivers/gpio/Kconfig:config GPIO_ALTERA
drivers/gpio/Kconfig: tristate "Altera GPIO"
...but however it does not include module.h -- it in turn gets it from
another header (gpio/driver.h) and we'd like to replace that with a
forward delcaration of "struct module;" but if we do, this file will
fail to compile.
So we fix this first to avoid putting build failures into the bisect
commit history.

This file is currently getting module.h from a global gpio header
and it will faii to build once we remove module.h from that.
However, the driver is controlled with the following Kconfig:
drivers/gpio/Kconfig:config GPIO_SX150X
drivers/gpio/Kconfig: bool "Semtech SX150x I2C GPIO expander"
and hence the two lines of MODULE_DEVICE_TABLE are no-ops that
can simply be deleted.

that did demodularization, however the unseen include prevented my
build testing from detecting it.

This reverts commit 313b9a9938bf4076425741121d5d766826793e5d.
This was already fixed by
commit bf62efeb164343916ebb89dca6dfe5e6b6751700
"gpio: pca954x: fix undefined error code from remove"
The latter is a better fix since it makes it easier to detect
erronous code by not assigning a default error code.

Using a default trigger is a bad idea if using DT to configure
interrupts, as the device's interrupt specifier will always contain
the trigger configuration.

having a default. Hopefully, the couple of drivers still using
this feature will quickly be fixed.

The Aspeed SoCs contain GPIOs banked by letter, where each bank contains
8 pins. The GPIO banks are then grouped in sets of four in the register
layout.
The implementation exposes multiple banks through the one driver and
requests and releases pins via the pinctrl subsystem. The hardware
supports generation of interrupts from all GPIO-capable pins.
A number of hardware features are not yet supported: Configuration of
interrupt direction (ARM or LPC), debouncing, and WDT reset tolerance
for output ports.

- Fix for the nd_blk (NVDIMM Block Window Aperture) driver.
A spec clarification requires the driver to mask off reserved bits in

- Fix for a kernel crash in the nvdimm unit tests when module loading
is interrupted with SIGTERM. Tagged for -stable since validation
efforts external to Intel use the unit tests for qualifying
backports.
- Add a new 'size' sysfs attribute for the BTT (NVDIMM Block
Translation Table) driver to make it symmetric with the other
namespace personality drivers (PFN and DAX) that provide a size
attribute for indicating how much namespace capacity is lost to
metadata.
The BTT change arrived at the start of the merge window and has
appeared in a -next release. It can technically wait for 4.9, but it
is small, fixes asymmetry in the libnvdimm-sysfs interface, and

When nvme_delete_queue fails in the first pass of the
nvme_disable_io_queues() loop, we return early, failing to suspend all
of the IO queues. Later, on the nvme_pci_disable path, this causes us
to disable MSI without actually having freed all the IRQs, which
triggers the BUG_ON in free_msi_irqs(), as show below.
This patch refactors nvme_disable_io_queues to suspend all queues before
start submitting delete queue commands. This way, we ensure that we
have at least returned every IRQ before continuing with the removal
path.

This patch adds support for the GPIO found in Broadcom's bcm63xx-gpio
chips.
This GPIO controller is used in the following Broadcom SoCs: BCM6338, BCM6345.
It can be used in newer SoCs, without the capability of pin multiplexing.
