The ADS1015 device have two operating modes, continuous conversion mode
and single-shot mode. This driver assumes that the continuous conversion
mode is selected by runtime resume callback when the ADC result is
requested.
If CONFIG_PM is disabled, the device is always in the default single-shot
mode and no one begins a single conversion. So the conversion register
doesn't contain valid ADC result. Fix it by changing the continuous mode
in probe function.

The ti-ads1015 driver supports ADS1015 and ADS1115 devices. The same
scale information is used for both devices in this driver, however they
have actually different values and the ADS1115's one is not correct.
These devices have the same full-scale input voltage range for each PGA
selection. So instead of adding another hardcoded scale information,
compute a correct scale on demand from each device's resolution.

The ti-ads1015 driver has eight iio voltage channels and each iio channel
can hold own sampling frequency information.
The ADS1015 device only have a single config register which contains an
input multiplexer selection, PGA and data rate settings. So the driver
should load the correct settings when the input multiplexer selection is
changed.
However, regardless of which channlel is currently selected, changing any
iio channel's sampling frequency information immediately overwrites the
current data rate setting in the config register.
It breaks the current data rate setting if the different channel's sampling
frequency information is changed because the data rate setting is not
reloaded when the input multiplexer is switched.
This removes the unexpected config register update and correctly load the
data rate setting before getting adc result.

It has been reported for a while that with iio-sensor-proxy service the
rotation only works after one suspend/resume cycle. This required a wait
in the systemd unit file to avoid race. I found a Yoga 900 where I could
reproduce this.
The problem scenerio is:
- During sensor driver init, enable run time PM and also set a
auto-suspend for 3 seconds.
This result in one runtime resume. But there is a check to avoid
a powerup in this sequence, but rpm is active
- User space iio-sensor-proxy tries to power up the sensor. Since rpm is
active it will simply return. But sensors were not actually
powered up in the prior sequence, so actaully the sensors will not work
- After 3 seconds the auto suspend kicks
If we add a wait in systemd service file to fire iio-sensor-proxy after
3 seconds, then now everything will work as the runtime resume will
actually powerup the sensor as this is a user request.
To avoid this:
- Remove the check to match user requested state, this will cause a
brief powerup, but if the iio-sensor-proxy starts immediately it will
still work as the sensors are ON.
- Also move the autosuspend delay to place when user requested turn off
of sensors, like after user finished raw read or buffer disable

wait_for_range_completion() is nicely busted when handling
wrapping of the command queue, leading to an early exit
instead of waiting for the command to have been executed.
Fortunately, the impact is pretty minor, as it only impair
the detection of an ITS that doesn't make any forward progress
for a whole second. And an ITS should *never* lock up.

the commit
9424693035a5 ("i2c: i801: Create iTCO device on newer Intel PCHs")
unconditionally hid the P2SB PCI device wrongly) it will make the

fail on ioremap().
Therefore, store the presence state of P2SB PCI device before unhiding
it for reading BAR and restore the presence state after reading BAR.

The config_log_add() function first calls config_log_put() with the
variable 'cld' and then jumps to label 'out_cld', which will call
the same function with the same 'cld' variable. However, at this
point, 'cld' might have been already freed by the first invocation
of config_log_put(). Even if we remove the invocation at that point,
we will still get into trouble. This is because, in the error path,
just below the label 'out_cld', we try to put 'params_cls' and
'sptlrpc_cld', which might also have been freed by config_log_put().
The point is that, config_llog_data::cld_sptlrpc and
config_llog_data::cld_params members are assigned at the beginning
of this function.
To avoid this, do not call config_log_put() inside the else block,
immediately jump to 'out_cld' instead. Moreover, remove assignments
to config_llog_data::cld_sptlrpc and config_llog_data::cld_params at
the beginning, since we already assign them below in the function
with 'cld_lock' held.
As an additional benefit, code size gets smaller.

As we know in some target's checkentry it may dereference par.entryinfo
to check entry stuff inside. But when sched action calls xt_check_target,
par.entryinfo is set with NULL. It would cause kernel panic when calling
some targets.
It can be reproduce with:
# tc qd add dev eth1 ingress handle ffff:
# tc filter add dev eth1 parent ffff: u32 match u32 0 0 action xt \
-j ECN --ecn-tcp-remove
It could also crash kernel when using target CLUSTERIP or TPROXY.
By now there's no proper value for par.entryinfo in ipt_init_target,
but it can not be set with NULL. This patch is to void all these
panics by setting it with an ipt_entry obj with all members = 0.
Note that this issue has been there since the very beginning.

rxrpc_service_prealloc_one() doesn't set the socket pointer on any new call
it preallocates, but does add it to the rxrpc net namespace call list.
This, however, causes rxrpc_put_call() to oops when the call is discarded
when the socket is closed. rxrpc_put_call() needs the socket to be able to
reach the namespace so that it can use a lock held therein.
Fix this by setting a call's socket pointer immediately before discarding
it.
This can be triggered by unloading the kafs module, resulting in an oops
like the following:

list.dev has not been initialized and so the copy_to_user is copying
data from the stack back to user space which is a potential
information leak. Fix this ensuring all of list is initialized to
zero.

enable_4k_uar module parameter was added in patch cited below to
address the backward compatibility issue in SRIOV when the VM has
system's PAGE_SIZE uar implementation and the Hypervisor has 4k uar
implementation.
The above compatibility issue does not exist in the non SRIOV case.
In this patch, we always enable 4k uar implementation if SRIOV
is not enabled on mlx4's supported cards.

If the pci_find_pcie_root_port() function is called on a root port
itself, return the root port rather than NULL.
This effectively reverts commit 0e405232871d6 ("PCI: fix oops when
try to find Root Port for a PCI device") which added an extra check
that would now be redundant.
