cpufreq: scmi: Fix null-ptr-deref in scmi_cpufreq_get_rate()
cpufreq_cpu_get_raw() can return NULL when the target CPU is not present
in the policy->cpus mask. scmi_cpufreq_get_rate() does not check for
this case, which results in a NULL pointer dereference.
Add NULL check after cpufreq_cpu_get_raw() to prevent this issue.
Fixes: 99d6bdf33877 ("cpufreq: add support for CPU DVFS based on SCMI message protocol")
