mainline inclusion from mainline-v7.1-rc1 commit db19103ea847ed139da59a2fb71773081c12cd40 category: bugfix bugzilla: https://atomgit.com/openeuler/kernel/issues/9134 CVE: NA Reference: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commi... ---------------------------------------------------------------------- The function acpi_processor_cstate_first_run_checks() is responsible for updating max_cstate and performing initial hardware validation. Currently, this function is invoked within acpi_processor_power_init(). However, the initialization flow already ensures this is called during acpi_processor_register_idle_driver(). Therefore, the call in acpi_processor_power_init() is redundant and effectively performs no work, so remove it.
