Stephen Kitt a00f6d3723 drivers/i2c: use simple i2c probe
All these drivers have an i2c probe function which doesn't use the
"struct i2c_device_id *id" parameter, so they can trivially be
converted to the "probe_new" style of probe with a single argument.

This is part of an ongoing transition to single-argument i2c probe
functions. Old-style probe functions involve a call to i2c_match_id:
in drivers/i2c/i2c-core-base.c,

         /*
          * When there are no more users of probe(),
          * rename probe_new to probe.
          */
         if (driver->probe_new)
                 status = driver->probe_new(client);
         else if (driver->probe)
                 status = driver->probe(client,
                                        i2c_match_id(driver->id_table, client));
         else
                 status = -EINVAL;

Drivers which don't need the second parameter can be declared using
probe_new instead, avoiding the call to i2c_match_id. Drivers which do
can still be converted to probe_new-style, calling i2c_match_id
themselves (as is done currently for of_match_id).

This change was done using the following Coccinelle script, and fixed
up for whitespace changes:

@ rule1 @
identifier fn;
identifier client, id;

- static int fn(struct i2c_client *client, const struct i2c_device_id *id)

Stephen Kitt a0542d2c45 macintosh/via-pmu-backlight: Use backlight helper
backlight_properties.fb_blank is deprecated. The states it represents
are handled by other properties; but instead of accessing those
properties directly, drivers should use the helpers provided by
backlight.h.

Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all
this and insulates this from future changes.

Stephen Kitt 3e98b9bd84 dmaengine: sh: Remove unused shdma-arm.h
shdma-arm.h was introduced with commit 1e69653d40 ("DMA: shdma: add
r8a73a4 DMAC data to the device ID table"), and its sole user was
removed with commit a19788612f ("dmaengine: sh: Remove R-Mobile APE6
support"). The latter mentions r8a73a4.dtsi but shdma support was
removed from that with commit cfda820377 ("ARM: dts: r8a73a4: Remove
non-functional DMA support"), so it seems this is safe to remove.

Stephen Kitt ad4fd3b1df drm: shmobile: Use backlight helper
This started with work on the removal of backlight_properties'
deprecated fb_blank field, much of which can be taken care of by using
helper functions provided by backlight.h instead of directly accessing
fields in backlight_properties. This patch series doesn't involve
fb_blank, but it still seems useful to use helper functions where
appropriate.

Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all
this and insulates this from future changes.

While we're at it, drop .fb_blank from the initialisation function; it

Stephen Kitt 72aef4f60f staging: olpc_dcon: Use backlight helper
Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all
this and insulates this from future changes.

Stephen Kitt 0924c5a0cb ipmi: use simple i2c probe function
The i2c probe functions here don't use the id information provided in
their second argument, so the single-parameter i2c probe function
("probe_new") can be used instead.

This avoids scanning the identifier tables during probes.

Stephen Kitt 32d4536133 docs: i2c: reference simple probes
Instead of documenting old-style probes, reference "simple probes" and
document the i2c_match_id function. This might help reduce the use of
two-argument probes in new code.

As part of the ongoing i2c transition to the simple probe
("probe_new"), this patch uses i2c_match_id to retrieve the
driver_data for the probed device. The id parameter is thus no longer
necessary and the simple probe can be used instead.

In the context of an i2c probe, i2c_match_id with the module id table
and the probed client never returns null, so removing the null check
on the i2c_device_id pointer is safe.

The i2c id tables are moved up before the probe function, as
suggested by Wolfram Sang, except where the existing code already had
a declaration for the of_device_id table.

Stephen Kitt 4fe6a63077 ASoC: SOF: Replace zero-length array with flexible-array member
There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use "flexible array members"[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].

This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().

Stephen Kitt 53944f171a mm: remove HARDENED_USERCOPY_FALLBACK
This has served its purpose and is no longer used.  All usercopy
violations appear to have been handled by now, any remaining instances
(or new bugs) will cause copies to be rejected.

This isn't a direct revert of commit 2d891fbc3b ("usercopy: Allow
strict enforcement of whitelists"); since usercopy_fallback is
effectively 0, the fallback handling is removed too.

This also removes the usercopy_fallback module parameter on slab_common.

the discard_max_bytes documentation section was renamed to
discard_max_hw_bytes, but the references it contains to
discard_max_bytes weren't updated.

This patch refers to discard_max_hw_bytes instead. It also reflows the
paragraph so that sentences end lines.

Many hwmon drivers don't use the id information provided by the old
i2c probe function, and the remainder can easily be adapted to the new

Drivers which didn't use the id are converted as-is; drivers which did

error-handling (if any) as before.

This patch wraps up the transition for hwmon, with four stragglers not
included in the previous large patch.

pmbus_do_probe doesn't use the id information provided in its second

Drivers which didn't use the id are converted as-is; drivers which did
are modified as follows:

* if the information in i2c_client is sufficient, that's used instead
  (client->name);
* configured v. probed comparisons are performed by comparing the
  configured name to the detected name, instead of the ids; this
  involves strcmp but is still cheaper than comparing all the device
  names when scanning the tables;
* anything else is handled by calling i2c_match_id() with the same
  level of error-handling (if any) as before.

Additionally, the mismatch message in the ltc2978 driver is adjusted
so that it no longer assumes that the driver_data is an index into
ltc2978_id.
