This occurs in selftests where the input and the output scatterlist point
to the same underlying memory (e.g., when tested with INPLACE_TWO_SGLISTS
mode).
The problem is that the hisi_sec2 driver maps these two different
scatterlists using the DMA_BIDIRECTIONAL flag which leads to overlapped
write mappings which are not supported by the DMA layer.
Fix it by using the fine grained and correct DMA mapping directions. While
at it, switch the DMA directions used by the hisi_zip driver too.

In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d2469 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping locks in atomic contexts.
Switch to the regular pointer formatting which is safer and
easier to reason about.

Panic notifiers are invoked with RCU read lock held and when the
SNP panic notifier tries to unregister itself from the panic
notifier callback itself it causes a deadlock as notifier
unregistration does RCU synchronization.
Code flow for SNP panic notifier:
snp_shutdown_on_panic() ->
__sev_firmware_shutdown() ->
__sev_snp_shutdown_locked() ->
atomic_notifier_chain_unregister(.., &snp_panic_notifier)

Since the CAAM on these SoCs is managed by another ARM core, called the
SECO (Security Controller) on iMX8QM and Secure Enclave on iMX8ULP, which
also reserves access to register page 0 suspend operations cannot touch
this page.
This is similar to when running OPTEE, where OPTEE will reserve page 0.
Track this situation using a new state variable no_page0, reflecting if
page 0 is reserved elsewhere, either by other management cores in SoC or
by OPTEE.
Replace the optee_en check in suspend/resume with the new check.
optee_en cannot go away as it's needed elsewhere to gate OPTEE specific
situations.
Fixes the following splat at suspend:

The drm_writeback_connector_cleanup have the signature:
static void drm_writeback_connector_cleanup(
struct drm_device *dev,
struct drm_writeback_connector *wb_connector)
But it is stored and used as a drmres_release_t
typedef void (*drmres_release_t)(struct drm_device *dev, void *res);
While the current code is valid and does not produce any warning, the
CFI runtime check (CONFIG_CFI_CLANG) can fail because the function
signature is not the same as drmres_release_t.
In order to fix this, change the function signature to match what is
expected by drmres_release_t.

An earlier patch marked one of the two CPU masks as 'static' to reduce stack

Normally this should be done using alloc_cpumask_var(), but since the
driver already has a static mask and the probe function is not called
concurrently, use the same trick for both.

On ChromiumOS devices, the `ecc_size` is set to 0 (check dmesg | grep ecc
to see `ecc: 0`): this disables ECC for ramoops region, even when
`ramoops.ecc=1` is given to kernel command line parameter.
Introduce `ecc_size` module parameter to provide a method to turn on ECC
for ramoops and set different values of ecc_size per devices.
A large `ecc_size` value can cause a kernel panic due to a constraint in
Reed-Solomon code library. The validation for this constraint should
belong to the common pstore RAM layer, not in each individual driver. So
this check is handled by a separate patch [1].

Previous commit 548d770c330c ("regulator: pca9450: Add support for mode
operations") added support for setting forced PWM mode on the buck
regulators for pca9450a and pca9450bc parts. However part pca9451a also
supports this feature, thus add support for it.

From the datasheet of the MAX17201/17205, the LSB should be "5.0μVh/RSENSE".
The current computation sets it at 0.5mAh=5.0μVh/10mOhm, which does not take
into account the value of rsense (which is in 10µV steps) which can be
different from 10mOhm.
Change the computation to fit the specs.

Before Rust 1.29.0, Clippy introduced the `cast_lossless` lint [1]:
> Rust’s `as` keyword will perform many kinds of conversions, including
> silently lossy conversions. Conversion functions such as `i32::from`
> will only perform lossless conversions. Using the conversion functions
> prevents conversions from becoming silently lossy if the input types
> ever change, and makes it clear for people reading the code that the
> conversion is lossless.
While this doesn't eliminate unchecked `as` conversions, it makes such
conversions easier to scrutinize. It also has the slight benefit of
removing a degree of freedom on which to bikeshed. Thus apply the
changes and enable the lint -- no functional change intended.

In Rust 1.63.0, Clippy introduced the `as_underscore` lint [1]:
> The conversion might include lossy conversion or a dangerous cast that
> might go undetected due to the type being inferred.
>
> The lint is allowed by default as using `_` is less wordy than always
> specifying the type.
Always specifying the type is especially helpful in function call
contexts where the inferred type may change at a distance. Specifying
the type also allows Clippy to spot more cases of `useless_conversion`.
The primary downside is the need to specify the type in trivial getters.
There are 4 such functions: 3 have become slightly less ergonomic, 1 was
revealed to be a `useless_conversion`.
While this doesn't eliminate unchecked `as` conversions, it makes such
conversions easier to scrutinize. It also has the slight benefit of
removing a degree of freedom on which to bikeshed. Thus apply the
changes and enable the lint -- no functional change intended.

Unloading and reloading the driver (e.g. when built as a module)
currently leads to errors trying to enable wake IRQ since it's already
enabled.
Use devm to manage this for us so it correctly gets disabled when
removing the driver.
Additionally, call device_init_wakeup() so that charger attach/remove
will trigger a wakeup by default.
