Currently intel_scu_ipc.c, intel_pmc_ipc.c and intel_punit_ipc.c
redundantly implements the same IPC features and has lot of code
duplication between them. This driver addresses this issue by grouping
the common IPC functionalities under the same driver.
+static const char *ipc_dev_err_string(struct intel_ipc_dev *ipc_dev,
+ int error)
+{
+ switch (error) {
+ case IPC_DEV_ERR_NONE:

+ case IPC_DEV_ERR_CMD_NOT_SERVICED:
+ return "Command not-serviced/Invalid param";
+ case IPC_DEV_ERR_UNABLE_TO_SERVICE:
+ return "Unable-to-service/Cmd-timeout";
+ case IPC_DEV_ERR_CMD_INVALID:
+ return "Command-invalid/Cmd-locked";
+ case IPC_DEV_ERR_CMD_FAILED:
+ return "Command-failed/Invalid-VR-id";
+ case IPC_DEV_ERR_EMSECURITY:
+ return "Invalid Battery/VR-Error";
+ case IPC_DEV_ERR_UNSIGNEDKERNEL:

Since it's continuous list you can define an array of messages like
const char * const *errors = {
[..._ERR_...] = "",
...
};
Also you can use enum in the header and define _ERR_MAX there.
Thus, code would be transformed to
if (error < _ERR_MAX)
return errors[error];
return "Unknown Command";
Thanks will fix it in next version.
