The max77851 driver is failing to build for Linux kernels v5.16 to v6.0
and the following error is seen ...
drivers/thermal/max77851_thermal.c:173:30: error: implicit declaration
of function 'devm_thermal_of_zone_register'; did you mean
'devm_thermal_zone_of_sensor_register'?
[-Werror=implicit-function-declaration]
thermal->tz_device = devm_thermal_of_zone_register(&pdev->dev, 0,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The function devm_thermal_of_zone_register() was introduced in Linux
kernel v6.1 and not v5.16.
Instead of relying on kernel version to determine if this function is
present using the conftest.sh script which checks the kernel that is
being compiled to see if this function is present or not. This is also
beneficial for working with 3rd party Linux kernels that may have
back-ported upstream changes into their kernel and so the kernel version
checks do not work either.

CONFIG_CAN_LEDS has been marked as BROKEN since Linux v4.19 and was
finally removed in Linux v5.19. Only compile support for LEDS if enabled
in the kernel. Long-term we need to move the MTTCAN driver to use
LEDS_TRIGGER_NETDEV.
This is a better solution for working with 3rd party Linux kernels that
may backport upstream changes to the kernel and hence are not compatible
with these existing version checks.

The function ioremap_prot() has been exported by the Linux kernel since
v5.9. However, it is only available if GENERIC_IOREMAP is enabled. Since
Linux v6.0, when the ARM64 __ioremap() function was removed, was
GENERIC_IOREMAP enabled for ARM64 by default. Rather than depend on
kernel version for selecting if ioremap_prot is used, use ioremap_prot
if GENERIC_IOREMAP is enabled.
This is a better solution for working with 3rd party Linux kernels that
may backport upstream changes to the kernel and hence are not compatible

For the assembly code in the NVMAP cache maintenance source file it is
only necessary to use the SYM_FUNC_START/END macros. For NVMAP we don't
need to use the SYM_FUNC_START/END_PI variants (which add the __pi
prefix for position independent code) because they are only needed for
assembly code called early in boot prior to virtualisation being
enabled. Therefore, simplify the code to simply use the
SYM_FUNC_START/END macros and remove the kernel version check.
