Change array index from the loop bound variable to loop index.
If a poll file fails to open for any intermediate device, all poll files with
fds of devices from 0 upto that device must be closed in the open_poll_files()
function. The current code only closes the poll file with the most recent fd
allocated, and at times tries to close the same file multiple times.

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

The loopback driver allows the user to set a minimum delay of up to one
second to be inserted between test iterations (i.e. request
submissions). The delay is currently specified in microseconds and is
implemented using udelay.
Busy looping for long periods is not just anti-social; udelay must not
be used for delays longer than a few milliseconds due to the risk of
integer overflow.
Replace the broken udelay with a usleep_range with a 100 us range for
short delays (< 20 ms) and otherwise revert to using msleep.

Currently we already have two pin configuration related callbacks
available for GPIO chips .set_single_ended() and .set_debounce(). In
future we expect to have even more, which does not scale well if we need
to add yet another callback to the GPIO chip structure for each possible
configuration parameter.
Better solution is to reuse what we already have available in the
generic pinconf.
To support this, we introduce a new .set_config() callback for GPIO
chips. The callback takes a single packed pin configuration value as
parameter. This can then be extended easily beyond what is currently
supported by just adding new types to the generic pinconf enum.
If the GPIO driver is backed up by a pinctrl driver the GPIO driver can
just assign gpiochip_generic_config() (introduced in this patch) to
.set_config and that will take care configuration requests are directed
to the pinctrl driver.
We then convert the existing drivers over .set_config() and finally
remove the .set_single_ended() and .set_debounce() callbacks.

Dummy codec register were initially added while populating dummy codec
mixer controls until module topology parser was available. Now, these
dummy registers are nowhere used and thus can be safely removed.
Since ASoC framework requires a valid callback for both read & write
register APIS, currently empty placeholders are kept to avoid panic.
Later, register mapping logic can be defined:
1. Assuming fixed number of maximum modules connected and register bits
corresponds to basic info of each module OR
2. With a logic to dynamically grow register_cache_size based on codec
modules added/removed.

While the timesync protocol was a great idea, it never ended up getting
implemented by any known hardware devices. It's also a bit
"interesting" in how it ties into the platform controller.
So, just remove it for now. It's not needed, no one uses it, and it's a
stumbling block in getting the greybus core code merged out of the
staging tree. If anyone wants it in the future, reverting this patch is
a great place to start from.

Fix coding style issue caught by checkpatch.pl related to the following
warning:
- CHECK: WARNING: line over 80 characters
This is done by dropping a redundant cast and by replacing the format specifier
in dev_err(); to "%zu" instead of "%d", in order to silence the warnings of the
compiler.
Also, while at it, drop the redundant cast in the comparison as well to maintain
consistency.

Currently the greybus-loopback thread logic spins around waiting for
send_count == iteration_max which on real hardware doesn't make a
difference to us but in simulation is excruciatingly slow, anti-social and
bad manners. Use the existing gb_loopback_async_wait_all() function to gate
continuing when the send_count == iteration_max and go to sleep until
there's something worthwhile to-do.

Pull vfs updates from Al Viro:
- more ->d_init() stuff (work.dcache)
- pathname resolution cleanups (work.namei)
- a few missing iov_iter primitives - copy_from_iter_full() and
friends. Either copy the full requested amount, advance the iterator
and return true, or fail, return false and do _not_ advance the
iterator. Quite a few open-coded callers converted (and became more
readable and harder to fuck up that way) (work.iov_iter)
- several assorted patches, the big one being logfs removal
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
logfs: remove from tree
vfs: fix put_compat_statfs64() does not handle errors
namei: fold should_follow_link() with the step into not-followed link
namei: pass both WALK_GET and WALK_MORE to should_follow_link()
namei: invert WALK_PUT logics
namei: shift interpretation of LOOKUP_FOLLOW inside should_follow_link()
namei: saner calling conventions for mountpoint_last()
namei.c: get rid of user_path_parent()
switch getfrag callbacks to ..._full() primitives
make skb_add_data,{_nocache}() and skb_copy_to_page_nocache() advance only on success

don't open-code file_inode()
ceph: switch to use of ->d_init()
