The calculation of the sampling point has min() and max() exchanged.
Fix this by using the clamp() helper instead.

There are several issues with the formula used for calculating the
deviation from the intended rate:
1. While min_err and last_stop are signed, srr and baud are unsigned.
Hence the signed values are promoted to unsigned, which will lead
to a bogus value of deviation if min_err is negative,
2. Srr is the register field value, which is one less than the actual
sampling rate factor,
3. The divisions do not use rounding.
Fix this by casting unsigned variables to int, adding one to srr, and
using a single DIV_ROUND_CLOSEST().

Commit 008258d995a6 ("clocksource/drivers/timer-ti-dm: Make
omap_dm_timer_set_load_start() static") made omap_dm_time_set_load_start
static because its prototype was not defined in a header. Unfortunately,
this causes a build warning on multi_v7_defconfig because this function
is not used anywhere in this translation unit:
drivers/clocksource/timer-ti-dm.c:589:12: error: unused function
'omap_dm_timer_set_load_start' [-Werror,-Wunused-function]
In fact, omap_dm_timer_set_load_start hasn't been used anywhere since
commit f190be7f39a5 ("staging: tidspbridge: remove driver") and the
prototype was removed in commit 592ea6bd1fad ("clocksource: timer-ti-dm:
Make unexported functions static"), which is probably where this should
have happened.

`vmk80xx_alloc_usb_buffers()` is called from `vmk80xx_auto_attach()` to
allocate RX and TX buffers for USB transfers. It allocates
`devpriv->usb_rx_buf` followed by `devpriv->usb_tx_buf`. If the
allocation of `devpriv->usb_tx_buf` fails, it frees
`devpriv->usb_rx_buf`, leaving the pointer set dangling, and returns an
error. Later, `vmk80xx_detach()` will be called from the core comedi
module code to clean up. `vmk80xx_detach()` also frees both
`devpriv->usb_rx_buf` and `devpriv->usb_tx_buf`, but
`devpriv->usb_rx_buf` may have already been freed, leading to a
double-free error. Fix it by removing the call to
`kfree(devpriv->usb_rx_buf)` from `vmk80xx_alloc_usb_buffers()`, relying
on `vmk80xx_detach()` to free the memory.

If `vmk80xx_auto_attach()` returns an error, the core comedi module code
will call `vmk80xx_detach()` to clean up. If `vmk80xx_auto_attach()`
successfully allocated the comedi device private data,
`vmk80xx_detach()` assumes that a `struct semaphore limit_sem` contained
in the private data has been initialized and uses it. Unfortunately,
there are a couple of places where `vmk80xx_auto_attach()` can return an
error after allocating the device private data but before initializing
the semaphore, so this assumption is invalid. Fix it by initializing
the semaphore just after allocating the private data in
`vmk80xx_auto_attach()` before any other errors can be returned.
I believe this was the cause of the following syzbot crash report

When SCSI blk-mq is enabled, there is a bug in handling errors in
scsi_queue_rq. Specifically, the bug is not setting result field of
scsi_request correctly when the dispatch of the command has been
failed. Since the upper layer code including the sg_io ioctl expects to
receive any error status from result field of scsi_request, the error is
silently ignored and this could cause data corruptions for some
applications.

Pull libnvdimm fixes from Dan Williams:
"I debated holding this back for the v5.2 merge window due to the size
of the "zero-key" changes, but affected users would benefit from
having the fixes sooner. It did not make sense to change the zero-key
semantic in isolation for the "secure-erase" command, but instead
include it for all security commands.
The short background on the need for these changes is that some NVDIMM
platforms enable security with a default zero-key rather than let the
OS specify the initial key. This makes the security enabling that
landed in v5.0 unusable for some users.
Summary:
- Compatibility fix for nvdimm-security implementations with a
default zero-key.
- Miscellaneous small fixes for out-of-bound accesses, cleanup after
initialization failures, and missing debug messages"

When a bond is enslaved to another bond, bond_netdev_event() only
handles the event as if the bond is a master, and skips treating the
bond as a slave.
This leads to a refcount leak on the slave, since we don't remove the
adjacency to its master and the master holds a reference on the slave.
Reproducer:
ip link add bondL type bond
ip link add bondU type bond
ip link set bondL master bondU
ip link del bondL

[Why]
On some compositors, with two monitors attached, VT terminal
switch can cause a graphical issue by the following means:
There are two streams, one for each monitor. Each stream has one
plane
current state:
M1:S1->P1
M2:S2->P2
The user calls for a terminal switch and a commit is made to
change both planes to linear swizzle mode. In atomic check,
a new dc_state is constructed with new planes on each stream
new state:
M1:S1->P3
M2:S2->P4
In commit tail, each stream is committed, one at a time. The first
stream (S1) updates properly, triggerring a full update and replacing
the state
current state:
M1:S1->P3
M2:S2->P4
The update for S2 comes in, but dc detects that there is no difference
between the stream and plane in the new and current states, and so
triggers a fast update. The fast update does not program swizzle,
so the second monitor is corrupted
[How]
Add a flag to dc_plane_state that forces full updates
When a stream undergoes a full update, set this flag on all changed
planes, then clear it on the current stream
Subsequent streams will get full updates as a result

Separate the overflow handling from the hardware interrupt status analysis.
The interrupt status is a single register and is common for all PFs. The
first PF reading the register is not necessarily the one who overflowed.
All PFs must check their overflow status on every attention.
In this change we clear the sticky indication in the attention handler to
allow doorbells to be processed again as soon as possible, but running
the doorbell recovery is scheduled for the periodic handler to reduce the
time spent in the attention handler.
Checking the need for DORQ flush was changed to "db_bar_no_edpm" because
qed_edpm_enabled()'s result could change dynamically and might have
prevented a needed flush.

When the DORQ (doorbell block) is overflowed, all PFs get attentions at the
same time. If one PF finished handling the attention before another PF even
started, the second PF might miss the DORQ's attention bit and not handle
the attention at all.
If the DORQ attention is missed and the issue is not resolved, another
attention will not be sent, therefore each attention is treated as a
potential DORQ attention.
As a result, the attention callback is called more frequently so the debug
print was moved to reduce its quantity.
The number of periodic doorbell recovery handler schedules was reduced
because it was the previous way to mitigating the missed attention issue.

DB_REC_DRY_RUN (running doorbell recovery without sending doorbells) is
never used. DB_REC_ONCE (send a single doorbell from the doorbell recovery)
is not needed anymore because by running the periodic handler we make sure
we check the overflow status later instead.
This patch is needed because in the next patches, the only doorbell
recovery type being used is DB_REC_REAL_DEAL, and the fixes are much
cleaner without this enum.

The err2 error return path calls qede_ptp_disable that cleans up
on an error and frees ptp. After this, the free'd ptp is dereferenced
when ptp->clock is set to NULL and the code falls-through to error
path err1 that frees ptp again.
Fix this by calling qede_ptp_disable and exiting via an error
return path that does not set ptp->clock or kfree ptp.

Code which initializes the "clk_init_data.ops" checks pll->rate_table
before that field is ever assigned to so it always picks
"clk_pll1416x_min_ops".
This breaks dynamic rate rounding for features such as cpufreq.
Fix by checking pll_clk->rate_table instead, here pll_clk refers to
the constant initialization data coming from per-soc clk driver.

This reverts commit 9fd097b14918875bd6f125ed699d7bbbba5893ee.
Instead of leaving disk->events completely empty, we now export the
supported events again, and tell the block layer not to forward events to
user space by not setting DISK_EVENT_FLAG_UEVENT. This allows the block
layer to distinguish between devices that for which events should be
handled in kernel only, and devices which don't support any meda change
events at all.

Currently, an empty disk->events field tells the block layer not to
forward media change events to user space. This was done in commit
7c88a168da80 ("block: don't propagate unlisted DISK_EVENTs to userland")
in order to avoid events from "fringe" drivers to be forwarded to user
space. By doing so, the block layer lost the information which events
were supported by a particular block device, and most importantly,
whether or not a given device supports media change events at all.
Prepare for not interpreting the "events" field this way in the future
any more. This is done by adding an additional field "event_flags" to
struct gendisk, and two flag bits that can be set to have the device
treated like one that had the "events" field set to a non-zero value
before. This applies only to the sd and sr drivers, which are changed to
set the new flags.
The new flags are DISK_EVENT_FLAG_POLL to enforce polling of the device
for synchronous events, and DISK_EVENT_FLAG_UEVENT to tell the
blocklayer to generate udev events from kernel events.
In order to add the event_flags field to struct gendisk, the events
field is converted to an "unsigned short"; it doesn't need to hold
values bigger than 2 anyway.
This patch doesn't change behavior.

The async_events field, intended to be used for drivers that support
asynchronous notifications about disk events (aka media change events),
isn't currently used by any driver, and apparently that has been that
way for a long time (if not forever). Remove it.

Currently rt2x00 devices retransmit the management frames with
incremented sequence number if hardware is assigning the sequence.
This is HW bug fixed already for non-QOS data frames, but it should
be fixed for management frames except beacon.
Without fix retransmitted frames have wrong SN:
AlphaNet_e8:fb:36 Vivotek_52:31:51 Authentication, SN=1648, FN=0, Flags=........C Frame is not being retransmitted 1648 1
AlphaNet_e8:fb:36 Vivotek_52:31:51 Authentication, SN=1649, FN=0, Flags=....R...C Frame is being retransmitted 1649 1
AlphaNet_e8:fb:36 Vivotek_52:31:51 Authentication, SN=1650, FN=0, Flags=....R...C Frame is being retransmitted 1650 1
With the fix SN stays correctly the same:

If the MT_TXD3_SN_VALID flag is not set in the tx descriptor, the hardware
assigns the sequence number. However, the rest of the code assumes that the
sequence number specified in the 802.11 header gets transmitted.
This was causing issues with the aggregation setup, which worked for the
initial one (where the sequence numbers were still close), but not for
further teardown/re-establishing of sessions.
Additionally, the overwrite of the TID sequence number in WTBL2 was resetting
the hardware assigned sequence numbers, causing them to drift further apart.
Fix this by using the software assigned sequence numbers

Pull IOMMU fix from Joerg Roedel:
"Fix an AMD IOMMU issue where the driver didn't correctly setup the
exclusion range in the hardware registers, resulting in exclusion
ranges being one page too big.
This can cause data corruption of the address of that last page is
used by DMA operations"

Pull drm fixes from Dave Airlie:
"Fixes across the driver spectrum this week, the mediatek fbdev support
might be a bit late for this round, but I looked over it and it's not
very large and seems like a useful feature for them.
Otherwise the main thing is a regression fix for i915 5.0 bug that
caused black screens on a bunch of Dell XPS 15s I think, I know at
least Fedora is waiting for this to land, and the udl fix is also for
a regression since 5.0 where unplugging the device would end badly.
core:
- make atomic hooks optional
i915:
- Revert a 5.0 regression where some eDP panels stopped working
- DSI related fixes for platforms up to IceLake
- GVT (regression fix, warning fix, use-after free fix)
amdgpu:
- Cursor fixes
- missing PCI ID fix for KFD
- XGMI fix
- shadow buffer handling after reset fix
udl:
- fix unplugging device crashes.
mediatek:
- stabilise MT2701 HDMI support
- fbdev support
tegra:
- fix for build regression in rc1.
sun4i:
- Allwinner A6 max freq improvements
- null ptr deref fix
dw-hdmi:
- SCDC configuration improvements
omap:
- CEC clock management policy fix"

The exlcusion range limit register needs to contain the
base-address of the last page that is part of the range, as
bits 0-11 of this register are treated as 0xfff by the
hardware for comparisons.
So correctly set the exclusion range in the hardware to the
last page which is _in_ the range.
