In the latest kernel versions system crashes were noticed occasionally
during suspend/resume. This occurs because the RZ SSI suspend trigger
(called from snd_soc_suspend()) is executed after rz_ssi_pm_ops->suspend()
and it accesses IP registers. After the rz_ssi_pm_ops->suspend() is
executed the IP clocks are disabled and its reset line is asserted.
Since snd_soc_suspend() is invoked through snd_soc_pm_ops->suspend(),
snd_soc_pm_ops is associated with soc_driver (defined in
sound/soc/soc-core.c), and there is no parent-child relationship between
soc_driver and rz_ssi_driver the power management subsystem does not
enforce a specific suspend/resume order between the RZ SSI platform driver
and soc_driver.
To ensure that the suspend/resume function of rz-ssi is executed after
snd_soc_suspend(), use NOIRQ_SYSTEM_SLEEP_PM_OPS().

In the Rust DRM device abstraction we need to allocate a struct
drm_device.
Currently, there are two options, the deprecated drm_dev_alloc() (which
does not support subclassing) and devm_drm_dev_alloc(). The latter
supports subclassing, but also manages the initial reference through
devres for the parent device.
In Rust we want to conform with the subclassing pattern, but do not want
to get the initial reference managed for us, since Rust has its own,
idiomatic ways to properly deal with it.
There are two options to achieve this.
1) Allocate the memory ourselves with a KBox.
2) Implement __drm_dev_alloc(), which supports subclassing, but is
unmanged.
While (1) would be possible, it would be cumbersome, since it would
require exporting drm_dev_init() and drmm_add_final_kfree().
Hence, go with option (2) and implement __drm_dev_alloc().

Worth noting is that while the temperature register offsets and layout

During wacom_parse_and_register() the code calls wacom_devm_kfifo_alloc
to allocate a fifo. During this operation it passes kfifo_alloc a
fifo_size of 0. Kfifo attempts to round the size passed to it to the
next power of 2 via roundup_pow_of_two (queue-type data structures
do this to maintain efficiency of operations).
However during this phase a problem arises when the roundup_pow_of_two()
function utilises a shift exponent of fls_long(n-1), where n is the
fifo_size. Since n is 0 in this case and n is also an unsigned long,
doing n-1 causes unsigned integer wrap-around to occur making the
fifo_size 4294967295. So the code effectively does fls_long(4294967295)
which results in 64. Returning back to roundup_pow_of_two(), the code
utilises a shift exponent of 64. When a shift exponent of 64 is used
on a 64-bit type such as 1UL it results in a shift-out-of-bounds.
The root cause of the issue seems to stem from insufficient validation
of wacom_compute_pktlen(), since in this case the fifo_size comes
from wacom_wac->features.pktlen. During wacom_parse_and_register()
the wacom_compute_pktlen() function sets the pktlen as 0.
To fix this, we should handle cases where wacom_compute_pktlen()
results in 0.
