In the Linux kernel, the following vulnerability has been resolved: 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() Do a runtime PM get at the probe function to make sure
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.
