Drop the redundant interrupt-in-running flag, which tried to keep track
of when the interrupt-in URB was in flight. This isn't needed since we
can stop the URB unconditionally in tower_abort_transfers() and the URB
can not be submitted while usb_kill_urb() is running anyway.

Since commit d4ead16f50 ("USB: prevent char device open/deregister
race") core prevents further calls to open() after usb_deregister_dev()
returns so there's no need to use the interface data for
synchronisation.
This effectively reverts commit 54d2bc068f ("USB: fix locking in
idmouse") with respect to the open-disconnect race.
Note that the driver already uses a present flag to suppress I/O post
disconnect (even if all USB I/O take place at open).

Bring powerpc in line with other architectures that support extending or
overriding the bootloader provided command line.
The current behaviour is most like CMDLINE_FROM_BOOTLOADER where the
bootloader command line is preferred but the kernel config can provide a
fallback so CMDLINE_FROM_BOOTLOADER is the default. CMDLINE_EXTEND can
be used to append the CMDLINE from the kernel config to the one provided
by the bootloader.

As Mathias pointed out, the hub enters Cold Attach Status state and
requires a warm reset. However usb_reset_device() bails out early when
the device is in suspended state, as its callers port_event() and
hub_event() don't always resume the device.
Since there's nothing wrong to reset a suspended device, allow
usb_reset_device() to do so to solve the issue.

Invoke EFI_RNG_PROTOCOL to seed the UEFI RNG table"). Within the stub,
a Linux-specific RNG seed UEFI config table will be seeded. The EFI routines
in the core kernel will pick that up later, yet still early during boot,
to seed the kernel entropy pool. If CONFIG_RANDOM_TRUST_BOOTLOADER, entropy

To handle all arch-specific peculiarities when calling an EFI protocol
function, a wrapper efi_call_proto() exists on all relevant architectures.
On arm/arm64, this is merely a plain function call. On x86, a special EFI
entry stub needs to be used, however, as the calling convention differs.
To make the efi/random stub arch-independent, use efi_call_proto()
instead of the existing non-portable calls to the EFI get_rng protocol
function. This also requires the addition of some typedefs.

of_gpiochip_add(), when fails, calls gpiochip_remove_pin_ranges().
ADD:
gpiochip_add_data_with_key() ->
of_gpiochip_add() -> (ERROR path)
gpiochip_remove_pin_ranges()
At the same time of_gpiochip_remove() calls exactly the above mentioned
function unconditionally and so does gpiochip_remove().
REMOVE:
gpiochip_remove() ->
gpiochip_remove_pin_ranges()
of_gpiochip_remove() ->
gpiochip_remove_pin_ranges()
Since gpiochip_remove() calls gpiochip_remove_pin_ranges() unconditionally,
we have duplicate call to the same function when it's not necessary.
Move gpiochip_remove_pin_ranges() from of_gpiochip_add() to gpiochip_add()
to avoid duplicate calls and be consistent with the explicit call in
gpiochip_remove().

With stmfx_pinctrl_gpio_init_valid_mask callback, gpio_valid_mask was used
to initialize gpiochip valid_mask for gpiolib. But gpio_valid_mask was not
yet initialized. gpio_valid_mask required gpio-ranges to be registered,
this is the case after gpiochip_add_data call. But init_valid_mask
callback is also called under gpiochip_add_data. gpio_valid_mask
initialization cannot be moved before gpiochip_add_data because
gpio-ranges are not registered.
So, it is not possible to use init_valid_mask callback.
To avoid this issue, get rid of valid_mask and rely on ranges.

The table of devicetree identifiers is annotated as __initconst
indicating that it can be discarded after kernel boot but it is
referenced from the driver struct which has no init annotation leading
to a linker warning:

The variable bcm_iproc_gpio_driver references

driver struct is correct so remove the annotation from the match table.

Drop the default spansion_quad_enable() method and replace it with
spansion_read_cr_quad_enable().
The function was buggy, it didn't care about the previous values
of the Status and Configuration Registers. spansion_read_cr_quad_enable()
is a Read-Modify-Write-Check function that keeps track of what were
the previous values of the Status and Configuration Registers.
In terms of instruction types sent to the flash, the only difference
between the spansion_quad_enable() and spansion_read_cr_quad_enable()
is that the later calls spi_nor_read_sr(). We can safely assume that all
flashes support spi_nor_read_sr(), because all flashes call it in
spi_nor_sr_ready(). The transition from spansion_quad_enable() to
spansion_read_cr_quad_enable() will not affect anybody, drop the buggy
