In the Linux kernel, the following vulnerability has been resolved: clk: spacemit: ccu_mix: fix inverted condition in ccu_mix_trigger_fc() Fix inverted condition that skips frequency change trigger, causing kernel panics during cpufreq scaling.

A flaw was found in the Linux kernel's clock (clk) driver for Spacemit's ccu_mix component. An inverted condition within the `ccu_mix_trigger_fc()` function can cause the system to skip frequency change triggers. This can lead to kernel panics during CPU frequency scaling, resulting in a Denial of Service (DoS) for the system.
