<linux/sched/signal.h>
We are going to split <linux/sched/signal.h> out of <linux/sched.h>, which
will have to be picked up from other headers and a couple of .c files.
Create a trivial placeholder <linux/sched/signal.h> file that just
maps to <linux/sched.h> to make this patch obviously correct and
bisectable.
Include the new header in the files that are going to need it.

Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.
Use BUILD_BUG_ON in a couple ATM drivers.
In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
is in my opinion is quite an achievement. Hopefully this patch inspires
someone else to trim vsprintf.c more.

Pull pin control updates from Linus Walleij:
"Pin control bulk changes for the v4.11 kernel cycle.
Core changes:
- Switch the generic pin config argument from 16 to 24 bits, only use
8 bits for the configuration type. We might need to encode more
information about a certain setting than we need to encode
different generic settings.
- Add a cross-talk API to the pin control GPIO back-end, utilizing
pinctrl_gpio_set_config() from GPIO drivers that want to set up a
certain pin configuration in the back-end.
This also includes the .set_config() refactoring of the GPIO chips,
so that they pass a generic configuration for things like
debouncing and single ended (typically open drain). This change has
also been merged in an immutable branch to the GPIO tree.
- Take hogs with a delayed work, so that we finalize probing a pin
controller before trying to get any hogs.
- For pin controllers putting all group and function definitions into
the device tree, we now have generic code to deal with this and it
is used in two drivers so far.
- Simplifications of the pin request conflict check.
- Make dt_free_map() optional.
Updates to drivers:
- pinctrl-single now use the generic helpers to generate dynamic
group and function tables from the device tree.
- Texas Instruments IOdelay configuration driver add-on to
pinctrl-single.
- i.MX: use radix trees to store groups and functions, use the new
generic group and function helpers to manage them.
- Intel: add support for hardware debouncing and 1K pull-down. New
subdriver for the Gemini Lake SoC.
- Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
- Aspeed: use syscon cross-dependencies to set up related bits in the
LPC host controller and display controller.
- Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs.
Add banks Y, Z, AA, AB and AC.
- AMD: support additional GPIO.
- STM32: set this controller to strict muxing mode. STM32H743 MCU
support.
- Allwinner sunxi: deep simplifications on how to support subvariants
of SoCs without adding to much SoC-specific data for each
subvariant, especially for sun5i variants. New driver for V3s SoCs.
New driver for the H5 SoC. Support A31/A31s variants with the new
variant framework.
- Mvebu: simplifications to use a MMIO and regmap abstraction. New
subdrivers for the 98DX3236, 98DX5241 SoCs.
- Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC
driver to access regmaps. Add infrastructure for pin-bank retention
control. Clean out the pin retention control from
arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly in
the Samsung pin control driver(s).
- Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.
- Qualcomm: use raw spinlock variants: this makes the qualcomm driver
realtime-safe"

Despite the CPPI 4.1 is a generic DMA, it is tied to USB.
On the DSPS, CPPI 4.1 interrupt's registers are in USBSS (the MUSB glue).
Currently, to enable / disable and clear interrupts, the CPPI 4.1 driver
maps and accesses to USBSS's register, which making CPPI 4.1 driver not
really generic.
Move the interrupt management to DSPS driver.

Drop two redundant NULL checks from usb_serial_console_disconnect().
The usb_serial_console_disconnect function is called from the
USB-serial-device disconnect callback when a device is going away. Hence
there is no need to check for the serial-device pointer being NULL.
The serial-device port pointers are stored in an array that is a member
of the serial struct so the address of the first member of the array
(which the array name decays to) is never NULL either.

Since commit 4a510969374a ("tty: Make tty_files_lock per-tty") a new
tty_struct spin lock is taken in the tty release path, but the
USB-serial-console hack was never updated hence leaving the lock of its
"fake" tty uninitialised. This was eventually detected by lockdep.
Make sure to initialise the new lock also for the fake tty to address
this regression.
Yes, this code is a mess, but cleaning it up is left for another day.

FTDI devices use a receive latency timer to periodically empty the
receive buffer and report modem and line status (also when the buffer is
empty).
When a break or error condition is detected the corresponding status
flags will be set on a packet with nonzero data payload and the flags
are not updated until the break is over or further characters are
received.
In order to avoid over-reporting break and error conditions, these flags
must therefore only be processed for packets with payload.
This specifically fixes the case where after an overrun, the error
condition is continuously reported and NULL-characters inserted until
further data is received.

Hi Greg,
In this series, it adds qualcomm USB2 support. The review process takes
more than half of year, thanks for Stephen Boyd's great work.
Most of patches at linux-next more than ten days, and the last two small
chipidea patches at my tree about one day, no warning is reported from
autobuild robot.
Thanks.
