Current driver has some asymmetry in the runtime PM calls. On lan78xx_open()
it will call usb_autopm_get() and unconditionally usb_autopm_put(). And
on lan78xx_stop() it will call only usb_autopm_put(). So far, it was
working only because this driver do not activate autosuspend by default,
so it was visible only by warning "Runtime PM usage count underflow!".
Since, with current driver, we can't use runtime PM with active link,
execute lan78xx_open()->usb_autopm_put() only in error case. Otherwise,
keep ref counting high as long as interface is open.

create_gpadl_header() creates a message header, and one or more message
bodies if the number of GPADL entries exceeds what fits in the
header. Currently the code for creating the message header is
duplicated in the two halves of the main "if" statement governing
whether message bodies are created.
Eliminate the duplication by making minor tweaks to the logic and
associated comments. While here, simplify the handling of memory
allocation errors, and use umin() instead of open coding it.
For ease of review, the indentation of sizable chunks of code is
*not* changed. A follow-on patch updates only the indentation.
No functional change.

A recent commit removing the use of screen_info introduced a logic
error. The error causes hvfb_getmem() to always return -ENOMEM
for Generation 2 VMs. As a result, the Hyper-V frame buffer
device fails to initialize. The error was introduced by removing
an "else if" clause, leaving Gen2 VMs to always take the -ENOMEM
error path.
Fix the problem by removing the error path "else" clause. Gen 2
VMs now always proceed through the MMIO memory allocation code,
but with "base" and "size" defaulting to 0.

Hyper-V hosts can omit the _SYNC flag to due a bug on resume from modern
suspend. In such a case, the guest may fail to update its time-of-day to
account for the period when it was suspended, and could proceed with a
significantly wrong time-of-day. In such a case when the guest is
significantly behind, fix it by treating a _SAMPLE the same as if _SYNC
was received so that the guest time-of-day is updated.
This is hidden behind param hv_utils.timesync_implicit.

Chip outputs are enabled[1] before actual reset is performed[2] which might
cause pin output value to flip flop if previous pin value was set to 1.
Fix that behavior by making sure chip is fully reset before all outputs are
enabled.
Flip-flop can be noticed when module is removed and inserted again and one of
the pins was changed to 1 before removal. 100 microsecond flipping is
noticeable on oscilloscope (100khz SPI bus).
For a properly reset chip - output is enabled around 100 microseconds (on 100khz
SPI bus) later during probing process hence should be irrelevant behavioral
change.

The way that best rdev is chosen:
1) If the read is sequential from one rdev:
- if rdev is rotational, use this rdev;
- if rdev is non-rotational, use this rdev until total read length
exceed disk opt io size;
2) If the read is not sequential:
- if there is idle disk, use it, otherwise:
- if the array has non-rotational disk, choose the rdev with minimal
inflight IO;
- if all the underlaying disks are rotational disk, choose the rdev
with closest IO;
There are no functional changes, just to make code cleaner and prepare
for following refactor.

If resync is in progress, read_balance() should find the first usable
disk, otherwise, data could be inconsistent after resync is done. raid1
and raid10 implement the same checking, hence factor out the checking
to make code cleaner.
Noted that raid1 is using 'mddev->recovery_cp', which is updated after
all resync IO is done, while raid10 is using 'conf->next_resync', which
is inaccurate because raid10 update it before submitting resync IO.
Fortunately, raid10 read IO can't concurrent with resync IO, hence there
is no problem. And this patch also switch raid10 to use
'mddev->recovery_cp'.

Commit 12cee5a8a29e ("md/raid1: prevent merging too large request") add
the case choose next idle in read_balance():
read_balance:
for_each_rdev
if(next_seq_sect == this_sector || dist == 0)
-> sequential reads
best_disk = disk;
if (...)
choose_next_idle = 1
continue;
for_each_rdev
-> iterate next rdev
if (pending == 0)
best_disk = disk;
-> choose the next idle disk
break;
if (choose_next_idle)
-> keep using this rdev if there are no other idle disk
contine
However, commit 2e52d449bcec ("md/raid1: add failfast handling for reads.")
remove the code:
- /* If device is idle, use it */
- if (pending == 0) {
- best_disk = disk;
- break;
- }
Hence choose next idle will never work now, fix this problem by
following:
1) don't set best_disk in this case, read_balance() will choose the best
disk after iterating all the disks;
2) add 'pending' so that other idle disk will be chosen;
3) add a new local variable 'sequential_disk' to record the disk, and if
there is no other idle disk, 'sequential_disk' will be chosen;

For raid1, each read will iterate all the rdevs from conf and check if
any rdev is non-rotational, then choose rdev with minimal IO inflight
if so, or rdev with closest distance otherwise.
Disk nonrot info can be changed through sysfs entry:
/sys/block/[disk_name]/queue/rotational
However, consider that this should only be used for testing, and user
really shouldn't do this in real life. Record the number of non-rotational
disks in conf, to avoid checking each rdev in IO fast path and simplify
read_balance() a little bit.

The current api is_badblock() must pass in 'first_bad' and
'bad_sectors', however, many caller just want to know if there are
badblocks or not, and these caller must define two local variable that
will never be used.
Add a new helper rdev_has_badblock() that will only return if there are
badblocks or not, remove unnecessary local variables and replace
is_badblock() with the new helper in many places.
There are no functional changes, and the new helper will also be used
later to refactor read_balance().

Nouveau deallocates a few buffers post GPU init which are required for GPU suspend/resume to function correctly.
This is likely not as big an issue on systems where the NVGPU is the only GPU, but on multi-GPU set ups it leads to a regression where the kernel module errors and results in a system-wide rendering freeze.
This commit addresses that regression by moving the two buffers required for suspend and resume to be deallocated at driver unload instead of post init.

Apparently the LSI / Agere FW643 can't recover after a Secondary Bus Reset
and requires a power-off or suspend/resume and rescan.
VFIO resets a device before assigning it to a VM, and the FW643 doesn't
support any other reset methods, so this problem prevented assignment of
FW643 to VMs.
Prevent use of Secondary Bus Reset for this device.
With this change, the FW643 can be assigned to VMs with VFIO. Note that it
will not be reset, resulting in leaking state between VMs and host.

Commit c5eb1190074c ("PCI / PM: Allow runtime PM without callback
functions") eliminated the need for PM callbacks in
pci_pm_runtime_suspend() and pci_pm_runtime_resume(), but
didn't do the same for pci_pm_runtime_idle().
Therefore, runtime suspend worked as long as the driver implemented at
least one PM callback. But if the driver doesn't implement any PM
callbacks at all (driver->pm is NULL), pci_pm_runtime_idle() returned
-ENOSYS, which prevented runtime suspend.
Modify pci_pm_runtime_idle() to allow PCI device power state transitions
without runtime PM callbacks and complete the original intention of commit
c5eb1190074c ("PCI / PM: Allow runtime PM without callback functions").

Fix the register value comparison in the `max31335_volatile_reg`
function for the interrupt status register.
MAX31335_STATUS1 macro definition corresponds to the actual
interrupt status register.

IRQ_DOMAIN is a hidden (not user visible) symbol. Users cannot set
it directly thru "make *config", so drivers should select it instead
of depending on it if they need it.
Relying on it being set for a dependency is risky.
Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.
Therefore, change the use of "depends on" for IRQ_DOMAIN to
"select" for RTC_DRV_MT6397.
Fixes: 04d3ba70a3c9 ("rtc: mt6397: add IRQ domain dependency")

ds1511_rtc_read_alarm was useless as it is only called at boot time so
the alarm members of pdata have not yet been set. Read the actual registers
so there is a chance to get a meaningful value.
Then, drop the alarm related members of pdata as they are not used anymore.
