Why do it twice?

Indentation is off.

You could change this to be one string of ifs as:

 
+static uint8_t
+get_running_host_id(void)
+{
+       struct utsname unameData;
+       uint8_t host_id = CPFL_INVALID_HOST_ID;
+
+       if (uname(&unameData) != 0)
+               PMD_INIT_LOG(ERR, "Cannot fetch node_name for host\n");
+       else if (strstr(unameData.nodename, "ipu_imc"))
+               PMD_INIT_LOG(ERR, "CPFL PMD cannot be running on IMC.");
+       else if (strstr(unameData.nodename, "ipu_acc"))
+               host_id = CPFL_HOST_ID_ACC;
+       else
+               host_id = CPFL_HOST_ID_HOST;
 
+       return host_id;
+}
