In certain situations, the sysfs for uncore may not be present when all
CPUs in a package are offlined and then brought back online after boot.
This issue can occur if there is an error in adding the sysfs entry due
to a memory allocation failure. Retrying to bring the CPUs online will
not resolve the issue, as the uncore_cpu_mask is already set for the
package before the failure condition occurs.
This issue does not occur if the failure happens during module
initialization, as the module will fail to load in the event of any
error.
To address this, ensure that the uncore_cpu_mask is not set until the
successful return of uncore_freq_add_entry().

When an APU exits HW sleep with no active wake sources the Linux kernel will
rapidly assert that the APU can enter back into HW sleep. This happens in a
few ms. Contrasting this to Windows, Windows can take 10s of seconds to
enter back into the resiliency phase for Modern Standby.
For some situations this can be problematic because it can cause leakage
from VDDCR_SOC to VDD_MISC and force VDD_MISC outside of the electrical
design guide specifications. On some designs this will trip the over
voltage protection feature (OVP) of the voltage regulator module, but it
could cause APU damage as well.
To prevent this risk, add an explicit sleep call so that future attempts
to enter into HW sleep will have enough time to settle. This will occur
while the screen is dark and only on cases that the APU should enter HW
sleep again, so it shouldn't be noticeable to any user.

The ACPI byte code inside the ACPI control method responsible for
handling the WMI method calls uses a global buffer for constructing
the return value, yet the ACPI control method itself is not marked
as "Serialized".
This means that calling WMI methods on this WMI device is not
thread-safe, as concurrent WMI method calls will corrupt the global
buffer.
Fix this by serializing the WMI method calls using a mutex.

The value returned by acpi_evaluate_integer() is not checked,
but the result is not always successful, so it is necessary to
add a check of the returned value.
If the result remains negative during three iterations of the loop,
then the uninitialized variable 'val' will be used in the clamp_val()
macro, so it must be initialized with the current value of the 'curr'
variable.
In this case, the algorithm should be less noisy.

T495, T495s, and E560 laptops have the FANG+FANW ACPI methods
(therefore fang_handle and fanw_handle are not NULL) but they do not
actually work, which results in a "No such device or address" error.
The DSDT table code for the FANG+FANW methods doesn't seem to do
anything special regarding the fan being secondary. The bug was
introduced in commit 57d0557dfa ("platform/x86: thinkpad_acpi: Add

via the FANG+FANW ACPI methods.
Add a quirk for T495, T495s, and E560 to avoid the FANG+FANW methods.
Fan access and control is restored after forcing the legacy non-ACPI

Some subdrivers make use of the global reference tpacpi_pdev during
initialization, which is called from the platform driver's probe.
However, after the commit 38b9ab80db ("platform/x86: thinkpad_acpi:
Move subdriver initialization to tpacpi_pdriver's probe.") this
variable is only properly initialized *after* probing and this can
result in a NULL pointer dereference.
In order to fix this without reverting the commit, register the platform
bundle in two steps, first create and initialize tpacpi_pdev, then
register the driver synchronously with platform_driver_probe(). This way
the benefits of commit 38b9ab80db are preserved.
Additionally, the commit 43fc63a1e8 ("platform/x86: thinkpad_acpi:
Move HWMON initialization to tpacpi_hwmon_pdriver's probe") introduced
a similar problem, however tpacpi_sensors_pdev is only used once inside
the probe, so replace the global reference with the one given by the
probe.

irq_domain_add_linear() is going away as being obsolete now. Switch to
the preferred irq_domain_create_linear(). That differs in the first
parameter: It takes more generic struct fwnode_handle instead of struct
device_node. The first parameter is NULL here so nothing else needs to
be done.

The drm_bridge structure contains an encoder pointer that is widely used
by bridge drivers. This pattern is largely documented as deprecated in
other KMS entities for atomic drivers.
However, one of the main use of that pointer is done in attach to just
call drm_bridge_attach on the next bridge to add it to the bridge list.
While this dereferences the bridge->encoder pointer, it's effectively
the same encoder the bridge was being attached to.
We can make it more explicit by adding the encoder the bridge is
attached to to the list of attach parameters. This also removes the need
to dereference bridge->encoder in most drivers.

In the general case, a driver doesn't know which of system shutdown or
reboot is the better action to take to protect hardware in an emergency
situation. For this reason, hw_protection_shutdown is going to be removed
in favor of hw_protection_trigger, which defaults to shutdown, but may be
configured at kernel runtime to be a reboot instead.
The ChromeOS EC situation is different as we do know that shutdown is the
correct action as the EC is programmed to force reset after the short
period, thus replace hw_protection_shutdown with __hw_protection_trigger
with HWPROT_ACT_SHUTDOWN as argument to maintain the same behavior.
No functional change.

There are a few problems in this code:
First, if amd_pmf_tee_init() fails then the function returns directly
instead of cleaning up. We cannot simply do a "goto error;" because
the amd_pmf_tee_init() cleanup calls tee_shm_free(dev->fw_shm_pool);
and amd_pmf_tee_deinit() calls it as well leading to a double free.
I have re-written this code to use an unwind ladder to free the
allocations.
Second, if amd_pmf_start_policy_engine() fails on every iteration though
the loop then the code calls amd_pmf_tee_deinit() twice which is also a
double free. Call amd_pmf_tee_deinit() inside the loop for each failed
iteration. Also on that path the error codes are not necessarily
negative kernel error codes. Set the error code to -EINVAL.
There is a very subtle third bug which is that if the call to
input_register_device() in amd_pmf_register_input_device() fails then
we call input_unregister_device() on an input device that wasn't
registered. This will lead to a reference counting underflow
because of the device_del(&dev->dev) in __input_unregister_device().
It's unlikely that anyone would ever hit this bug in real life.
