Subject: [PATCH v2 02/14] ACPI: CPPC: Fix kernel doc warnings
Kernel doc validation script is unhappy and complains with the below set
of warnings.
| drivers/acpi/cppc_acpi.c:560: warning: Function parameter or member
| 'pcc_ss_id' not described in 'pcc_data_alloc'
| drivers/acpi/cppc_acpi.c:1343: warning: Function parameter or member
| 'cpu_num' not described in 'cppc_get_transition_latency'
Fix it.
