cpufreq: phytium: bugfix the null pointer of boost in high temperature

[JiakunShuai]

Fix that when the temperature cotrol module determines whether boost is supported of not in a high temperature enviroment and boost is not enabled, the error code will be retured because the cpufreq_driver module is not initialized, resulting in entering the cpufreq module and writing a value to it, and a null pointer error will be reported.

Summary by Sourcery

Bug Fixes:

• Return 0 instead of -EINVAL in cpufreq_boost_supported() and cpufreq_boost_enabled() when the driver is uninitialized to prevent null pointer dereferences

Reviewer's Guide

Error paths in CPU frequency boost support now return false instead of an error code when the driver isn’t initialized, preventing null pointer dereferences in high-temperature scenarios.

Hi @JiakunShuai. Thanks for your PR.

I'm waiting for a deepin-community member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
