devm_ioremap_resource does sanity checks on the given resource. No need to
duplicate this in the driver.

This patch changes the driver to avoid the usage of IS_ERR_OR_NULL()
macro. This macro can lead to dangerous results, like returning
success (0) during a failure scenario (NULL pointer handling).

The case present in this driver can be translated to a simple
check for IS_ERR(), as the cpufreq_cooling_register() returns
either a valid pointer or an ERR_PTR().

This patch changes the driver to avoid the usage of IS_ERR_OR_NULL()
macro. This macro can lead to dangerous results, like returning
success (0) during a failure scenario (NULL pointer handling).

The case present in this patch has simply be translated to
normal check for NULL and if the pointer has an error code.
The later case is needed because functions like
thermal_zone_get_zone_by_name() could return an ERR_PTR().

they match open parenthesis, like checkpatch.pl --strict

There are at least three patterns for oneline comments in this
file. This patch changes them to one single pattern

Just for code readiness, this patch makes all functions
on this file to have a blank line before their returns.
Now, some functions follow this pattern, and others will
not have a blank line. So, this patch makes it a single
pattern.
