strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().
Direct replacement is safe here since return value of -errno
is used to check for truncation instead of sizeof(dest).

While there is probably only ever a single instance of such a pcmtst
device, it's still bad style to use a static variable to store per
device data. Make use of platform_get_drvdata() and
platform_set_drvdata() which fixes a data corruption if there should be
two or more such devices (or this driver is used as a template for
another driver).

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

As of today, the only cool and legal way to get ARM64 SMP going is
via PSCI (or spin tables). Sadly, not all chip and device vendors were
considerate of this in the early days of arm64. Qualcomm, for example
reused their tried-and-true spin-up method from MSM8974 and their Krait/
arm32 Cortex designs.
MSM8916 supports SMP with its arm32 dt overlay, as probably could 8939.
But the arm64 DT should not define non-PSCI SMP or CPUidle stuff.
Drop the qcom,idle-state-spc compatible (associated with Qualcomm-specific
CPUIdle) to make the dt checker happy:
apq8039-t2.dtb: idle-states: cpu-sleep-0:compatible:

Unless explicitly specified the interrupt-parent property is inherited

compliance with the devicetree specification.
Following commit 2d5cab9232 ("arm64: dts: qcom: sc8280xp-pmics:
Specify interrupt parent explicitly"), add an explicit interrupt parent
also for the PMIC RTC node for the benefit of other operating systems
which may be confused by this omission.
Note that any such OS must still implement a fallback to the root
interrupt domain as most devicetrees are written under the assumption
that the interrupt parent is inherited.
