[PATCH] cpufreq: loongson3: Use raw_smp_processor_id() in do_service_request()

From: Huacai Chen
Date: Wed Aug 28 2024 - 02:25:25 EST


Use raw_smp_processor_id() instead of plain smp_processor_id() in
do_service_request(), otherwise we may get some errors with the driver
enabled:

BUG: using smp_processor_id() in preemptible [00000000] code: (udev-worker)/208
caller is loongson3_cpufreq_probe+0x5c/0x250 [loongson3_cpufreq]
