clk: mediatek: Do a runtime PM get on controllers during probe
CWE ID: N/A
Base Score (CVSS): N/A
CVE: CVE-2024-27002
Descrizione: In the Linux kernel, the following vulnerability has been fixed: clk: mediatek: Do a runtime PM get on controllers during probe mt8183-mfgcfg has a mutual dependency with genpd during the probing stage, which leads to a deadlock in the following call stack: CPU0: genpd_lock –> clk_prepare_lock genpd_power_off_work_fn() genpd_lock() generic_pm_domain::power_off() clk_unprepare() clk_prepare_lock() CPU1: clk_prepare_lock –> genpd_lock clk_register() __clk_core_init() clk_prepare_lock() clk_pm_runtime_get() genpd_lock() Perform a runtime PM get at the probe function to ensure clk_register() won’t acquire the genpd lock. Instead of only modifying mt8183-mfgcfg, do this on all mediatek clock controller probings because we don’t believe this would cause any regression. Verified on MT8183 and MT8192 Chromebooks.
