Masahiro Yamada a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Linus Torvalds 80ef846e99 Staging/IIO driver patches for 5.8-rc1
Here is the large set of staging and IIO driver changes for 5.8-rc1
 
 Nothing major, but a lot of new IIO drivers are included in here, along
 with other core iio cleanups and changes.
 
 On the staging driver front, again, nothing noticable.  No new deletions
 or additions, just a ton of tiny cleanups all over the tree done by a
 lot of different people.  Most coding style, but many actual real fixes
 and cleanups that are nice to see.
 
 All of these have been in linux-next for a while with no reported
 issues.

Ulf Hansson 1be64c7963 mmc: host: Drop redundant MMC_CAP_ERASE
The MMC_CAP_ERASE bit is no longer used by the mmc core as erase, discard
and trim operations are now always supported. Therefore, drop the bit and
move all mmc hosts away from using it.

Ulf Hansson a389087ee9 staging: greybus: sdio: Respect the cmd->busy_timeout from the mmc core
Using a fixed 1s timeout for all commands is a bit problematic.

For some commands it means waiting longer than needed for the timeout to
expire, which may not a big issue, but still. For other commands, like for
an erase (CMD38) that uses a R1B response, may require longer timeouts than
1s. In these cases, we may end up treating the command as it failed, while
it just needed some more time to complete successfully.

Fix the problem by respecting the cmd->busy_timeout, which is provided by
the mmc core.

Johan Hovold 6064aeefa8 staging: greybus: uart: replace driver line-coding struct
Drop the driver version of the line-coding request and use the protocol
definition directly as was originally intended instead.

This specifically avoids having the two versions of what is supposed to
be the same struct ever getting out of sync.

Note that this has in fact already happened once when the protocol
definition had its implicit padding removed while the driver struct
wasn't updated. The fact that we used the size of the then larger driver
struct when memcpying its content to the stack didn't exactly make
things better. A later addition of a flow-control field incidentally
made the structures match again.

Johan Hovold ae62cf5eb2 staging: greybus: loopback_test: fix potential path truncations
Newer GCC warns about possible truncations of two generated path names as
we're concatenating the configurable sysfs and debugfs path prefixes
with a filename and placing the results in buffers of the same size as
the maximum length of the prefixes.

	snprintf(d->name, MAX_STR_LEN, "gb_loopback%u", dev_id);

	snprintf(d->sysfs_entry, MAX_SYSFS_PATH, "%s%s/",
		 t->sysfs_prefix, d->name);

	snprintf(d->debugfs_entry, MAX_SYSFS_PATH, "%sraw_latency_%s",
		 t->debugfs_prefix, d->name);

Fix this by separating the maximum path length from the maximum prefix
length and reducing the latter enough to fit the generated strings.

Note that we also need to reduce the device-name buffer size as GCC
isn't smart enough to figure out that we ever only used MAX_STR_LEN
bytes of it.

Gustavo A. R. Silva 5979afa2c4 staging: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Dan Carpenter 329101244f staging: greybus: light: fix a couple double frees
The problem is in gb_lights_request_handler().  If we get a request to
change the config then we release the light with gb_lights_light_release()
and re-allocated it.  However, if the allocation fails part way through
then we call gb_lights_light_release() again.  This can lead to a couple
different double frees where we haven't cleared out the original values:

	gb_lights_light_v4l2_unregister(light);
	...
	kfree(light->channels);
	kfree(light->name);

I also made a small change to how we set "light->channels_count = 0;".
The original code handled this part fine and did not cause a use after
free but it was sort of complicated to read.

Gustavo A. R. Silva 827c085bae staging: greybus: power_supply: use struct_size() helper
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.

So, replace code of the following form:

sizeof(*resp) + props_count * sizeof(struct gb_power_supply_props_desc)

with:

struct_size(resp, props, props_count)

This code was detected with the help of Coccinelle.

Johan Hovold 47830c1127 staging: greybus: power_supply: fix prop-descriptor request size
Since moving the message buffers off the stack, the dynamically
allocated get-prop-descriptor request buffer is incorrectly sized due to
using the pointer rather than request-struct size when creating the
operation.

Fortunately, the pointer size is always larger than this one-byte
request, but this could still cause trouble on the remote end due to the
unexpected message size.

Remove print statement following unsuccessful kmalloc when there
