Pull driver core fixes from Greg KH:
"Here are some driver core fixes for 5.0-rc6.
Well, not so much "driver core" as "debugfs". There's a lot of
outstanding debugfs cleanup patches coming in through different
subsystem trees, and in that process the debugfs core was found that
it really should return errors when something bad happens, to prevent
random files from showing up in the root of debugfs afterward. So
debugfs was fixed up to handle this properly, and then two fixes for
the relay and blk-mq code was needed as it was making invalid
assumptions about debugfs return values.
There's also a cacheinfo fix in here that resolves a tiny issue.
All of these have been in linux-next for over a week with no reported
problems"

Fixed regulators do not have associated bus addresses and are typically
placed directly under the root node where their names must still be
unique despite not having a unit address.
Fix the malformed example node which had a unit address but no "reg"
property by dropping the unit address.
Also, try to make the example more useful by using the recommended
generic node name "regulator", but with a suffix reflecting the
regulator name in order to make it unique.

In the commit 62ba568f7aef ("ALSA: pcm: Return 0 when size <
start_threshold in capture"), we changed the behavior of
__snd_pcm_lib_xfer() to return immediately with 0 when a capture
stream has a high start_threshold. This was intended to be a
correction of the behavior consistency and looked harmless, but this
was the culprit of the recent breakage reported by syzkaller, which
was fixed by the commit e190161f96b8 ("ALSA: pcm: Fix tight loop of
OSS capture stream").
At the time for the OSS fix, I didn't touch the behavior for ALSA
native API, as assuming that this behavior actually is good. But this
turned out to be also broken actually for a similar deployment,
e.g. one thread goes to a write loop in blocking mode while another
thread controls the start/stop of the stream manually.
Overall, the original commit is harmful, and it brings less merit to
keep that behavior. Let's revert it.

In the case of SAE AP, drivers offload authentication to user-space
software, e.g. hostapd. For FullMAC drivers the procedure is as follows.
If auth_type is SAE and user space indicates external authentication
capability, then driver requests authentication offload to user-space
software using cfg80211_external_auth_request call. From that point,
auth frame exchange is performed transparently for driver: user-space
software sends/receives mgmt frames using mgmt_tx/mgmt_frame_register
cfg80211 callbacks. As soon as authenitcation is completed, user-space
software notifies driver about its status using external_auth cfg80211
callback.

So far there were two monitor frame formats:
1) 802.11 frames (with frame (sub)type & all addresses)
2) 802.11 frames with the radiotap header
Testing the latest FullMAC firmwares for 4366b1/4366c0 resulted in
discovering a new format being used. It seems (almost?) identical to the
one known from ucode used in SoftMAC devices which is most likely the
same codebase anyway.
While new firmwares will /announce/ radiotap header support using the
"rtap" fw capability string it seems no string was added for the new
ucode header format.
All above means that:
1) We need new format support when dealing with a received frame
2) A new feature bit & mapping quirks have to be added manually
As for now only an empty radiotap is being created. Adding support for
extracting some info (band, channel, signal, etc.) is planned for the
future.

So far __brcmf_err() was using pr_err() which didn't allow identifying
device that was affected by an error. It's crucial for systems with more
than 1 device supported by brcmfmac (a common case for home routers).
This change allows passing struct brcmf_bus to the __brcmf_err(). That
struct has been agreed to be the most common one. It allows accessing
struct device easily & using dev_err() printing helper.

The recent commit fe0937b24ff5 ("x86/mm/cpa: Fold cpa_flush_range() and
cpa_flush_array() into a single cpa_flush() function") accidentally made
the call to make_addr_canonical_again() go away, which breaks
set_mce_nospec().
Re-instate the call to convert the address back into canonical form right
before invoking either CLFLUSH or INVLPG. Rename the function while at it
to be shorter (and less MAGA).

1. When checking if IE is in the frame, it uses just the ID, which
