The cppc_ffh_csr_read() and cppc_ffh_csr_write() returns Linux error code in "data->ret.error" so cpc_read_ffh() and cpc_write_ffh() must not use sbi_err_map_linux_errno() for FFH_CPPC_CSR.

The driver uses either SBI CPPC interfaces or the CSRs to access the CPPC registers as defined by the RISC-V FFH spec.
