Here are some staging and IIO driver fixes for 5.4-rc3.
The "biggest" thing here is a removal of the fbtft device and flexfb
code as they have been abandoned by their authors and are no longer
needed for that hardware.
Other than that, the usual amount of staging driver and iio driver fixes
for reported issues, and some speakup sysfs file documentation, which
has been long awaited for.
All have been in linux-next with no reported issues.

Here are a lot of small USB driver fixes for 5.4-rc3.
syzbot has stepped up its testing of the USB driver stack, now able to
trigger fun race conditions between disconnect and probe functions.
Because of that we have a lot of fixes in here from Johan and others
fixing these reported issues that have been around since almost all
time.
We also are just deleting the rio500 driver, making all of the syzbot
bugs found in it moot as it turns out no one has been using it for years
as there is a userspace version that is being used instead.
There are also a number of other small fixes in here, all resolving
reported issues or regressions.
All have been in linux-next without any reported issues.

Describe the fallthrough pseudo-keyword.

Miguel Ojeda comments on the eventual [[fallthrough]] syntax:
"Note that C17/C18 does not have [[fallthrough]].
C++17 introduced it, as it is mentioned above. I would keep the
__attribute__((fallthrough)) -> [[fallthrough]] change you did,
though, since that is indeed the standard syntax (given the paragraph
references C++17).
I was told by Aaron Ballman (who is proposing them for C) that it is
more or less likely that it becomes standardized in C2x. However, it
is still not added to the draft (other attributes are already,
though). See N2268 and N2269:
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2268.pdf (fallthrough)
http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2269.pdf (attributes in general)"

Reserve the pseudo keyword 'fallthrough' for the ability to convert the
various case block /* fallthrough */ style comments to appear to be an
actual reserved word with the same gcc case block missing fallthrough
warning capability.
All switch/case blocks now should end in one of:
break;
fallthrough;
goto <label>;
return [expression];
continue;
In C mode, GCC supports the __fallthrough__ attribute since 7.1,
the same time the warning and the comment parsing were introduced.
fallthrough devolves to an empty "do {} while (0)" if the compiler
version (any version less than gcc 7) does not support the attribute.

Commit 4b708b7b1a ("firmware: google: check if size is valid when
decoding VPD data") adds length checks, but the new vpd_decode_entry()
function botched the logic -- it adds the key length twice, instead of
adding the key and value lengths separately.
On my local system, this means vpd.c's vpd_section_create_attribs() hits
an error case after the first attribute it parses, since it's no longer
looking at the correct offset. With this patch, I'm back to seeing all
the correct attributes in /sys/firmware/vpd/...

We have two ways a request can be deferred:
1) It's a regular request that depends on another one
2) It's a timeout that tracks completions
We have a shared helper to determine whether to defer, and that
attempts to make the right decision based on the request. But we
only have some of this information in the caller. Un-share the
two timeout/defer helpers so the caller can use the right one.
