Furquan Shaikh 338d668b6f soc/intel/tigerlake: Fix NULL being passed for response buffer ... `pmc_send_ipc_cmd()` expects the caller to pass in a pointer to a valid request and response buffer. However, early_tcss driver was passing in a NULL pointer for response buffer which would result in invalid access by `pmc_send_ipc_cmd()`. Currently, the response buffer is not used in `update_tcss_mux()`. So, this change drops the passing of `rbuf` parameter to `send_pmc*` helpers and instead uses a local `rsp` variable in the respective functions. All the PMC functions used in early_tcss driver return some kind of response. These should be checked to return appropriate response code back to the caller. However, this needs to be done as a separate change.
