Many comments above functions start with a kernel doc indicator, but
the comments are not using kernel doc style. Get rid of the warnings
by simply removing the indicator.
E.g.:
drivers/s390/crypto/zcrypt_msgtype6.c:111: warning:
This comment starts with '/**', but isn't a kernel-doc comment.

Add __nonstring annotation, since the missing string termination for
id member of sclp_trace_entry is intended. This way we get rid of this

Support for expanded storage was only available until z13 and z/VM 6.3
respectively. However there haven't been any use cases a long time
before for this device driver.

The devices owned by the parent-driver (css) was getting unregistered
from the io-subchannel driver is clearly a layering violation.
Remove the subchannel unregistration from the child-drivers.
This also means, if the device connected to the subchannel is not
operational, or not accessible, the subchannel will not be unregistered.
Instead the CIO layer will allow valid subchannels without any operational
devices in sysfs. And the userspace tooling might need to be modified to
optimally handle this new situation.

The Linux console's VT102 implementation already consumes OSC
("Operating System Command") sequences, probably because that's how
palette changes are transmitted.
In addition to OSC, there are three other major clases of ANSI control
strings: APC ("Application Program Command"), PM ("Privacy Message"),
and DCS ("Device Control String"). They are handled similarly to OSC in
terms of termination.
Source: vt100.net
Add three new enumerated states, one for each of these types. All three
are handled the same way right now--they simply consume input until
terminated. I hope to expand upon this firmament in the future. Add
new predicate ansi_control_string(), returning true for any of these
states. Replace explicit checks against ESosc with calls to this
function. Transition to these states appropriately from the escape
initiation (ESesc) state.
This was motivated by the following Notcurses bugs:
https://github.com/dankamongmen/notcurses/issues/2050
https://github.com/dankamongmen/notcurses/issues/1828
https://github.com/dankamongmen/notcurses/issues/2069
where standard VT sequences are not consumed by the Linux console. It's
not necessary that the Linux console *support* these sequences, but it
ought *consume* these well-specified classes of sequences.
Tested by sending a variety of escape sequences to the console, and
verifying that they still worked, or were now properly consumed.
Verified that the escapes were properly terminated at a generic level.
Verified that the Notcurses tools continued to show expected output on
the Linux console, except now without escape bleedthrough.

This reverts commit 419dd626e357e89fc9c4e3863592c8b38cfe1571.
It turned out that the change from the reverted commit breaks the ACPI
based rpi's because it causes the 100Mhz max clock to be overridden to the
return from sdhci_iproc_get_max_clock(), which is 0 because there isn't a
OF/DT based clock device.

If the endpoint completion callback is call right after the ep_enabled flag
is cleared and before usb_ep_dequeue() is call, we could do a double free
on the request and the associated buffer.
Fix this by clearing ep_enabled after all the endpoint requests have been

When the uac2 function is stopped, there seems to be an issue reported on
some platforms (Intel Merrifield at least)
BUG: kernel NULL pointer dereference, address: 0000000000000008
...
RIP: 0010:dwc3_gadget_del_and_unmap_request+0x19/0xe0

The issue happens only when the gadget is using the sync type "async", not
"adaptive". This indicates that problem is coming from the feedback
endpoint, which is only used with async synchronization mode.
The problem is that request is freed regardless of usb_ep_dequeue(), which
ends up badly if the request is not actually dequeued yet.
Update the feedback endpoint free function to release the endpoint the same
way it is done for the data endpoint, which takes care of the problem.

When running as Xen PV guest, masking MSI-X is a responsibility of the
hypervisor. The guest has no write access to the relevant BAR at all - when
it tries to, it results in a crash like this:
BUG: unable to handle page fault for address: ffffc9004069100c
#PF: supervisor write access in kernel mode
#PF: error_code(0x0003) - permissions violation
RIP: e030:__pci_enable_msix_range.part.0+0x26b/0x5f0

(...)
The recently introduced function msix_mask_all() does not check the global
variable pci_msi_ignore_mask which is set by XEN PV to bypass the masking
of MSI[-X] interrupts.
Add the check to make this function XEN PV compatible.

If for any reason the interrupt enable for an ap queue fails the
state machine run for the queue returned wrong return codes to the
caller. So the caller assumed interrupt support for this queue in
enabled and thus did not re-establish the high resolution timer used
for polling. In the end this let to a hang for the user space process
waiting "forever" for the reply.
This patch reworks these return codes to return correct indications
for the caller to re-establish the timer when a queue runs without
interrupt support.
Please note that this is fixing a wrong behavior after a first
failure (enable interrupt support for the queue) failed. However,
looks like this occasionally happens on KVM systems.

This reverts commit ce78ffa3ef1681065ba451cfd545da6126f5ca88.
Wren and Nicolas reported that ath11k was failing to initialise QCA6390
Wi-Fi 6 device with error:
qcom_mhi_qrtr: probe of mhi0_IPCR failed with error -22
Commit ce78ffa3ef16 ("net: really fix the build..."), introduced in
v5.14-rc5, caused this regression in qrtr. Most likely all ath11k
devices are broken, but I only tested QCA6390. Let's revert the broken
commit so that ath11k works again.

The commit 71f642833284 ("ACPI: utils: Fix reference counting in
for_each_acpi_dev_match()") moved adev assignment outside of error
path and hence made acpi_dev_put(sensor->adev) a no-op. We still
need to drop reference count on error path, and to achieve that,
replace sensor->adev by locally assigned adev.

Currently, when query PFC configuration by dcbtool, driver will return
PFC enable status based on TC. As all priorities are mapped to TC0 by
default, if TC0 is enabled, then all priorities mapped to TC0 will be
shown as enabled status when query PFC setting, even though some
priorities have never been set.
for example:
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off
$ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on
To fix this problem, just returns user's PFC config parameter saved in
driver.

In bond 4, when the link goes down and up repeatedly, the bond may get an
unknown speed, and then this port can not work.
The driver notify netif_carrier_on() before update the link state, when the
bond receive carrier on, will query the speed of the port, if the query
operation happens before updating the link state, will get an unknown
speed. So need to notify netif_carrier_on() after update the link state.
