   Does someone know what this snippet in 
`arch/risc-v/src/esp32c3/esp32c3_wifi_adapter.c` should do, people on espressif 
/ anyone ? Blame points to @donghengqaz:
   ```
   
   static void *esp_thread_semphr_get(void)
   {
     int ret;
     int i;
     void *sem;
     struct tcb_s *tcb = this_task();
     struct task_group_s *group = tcb->group;
   
     for (i = 0; i < CONFIG_SCHED_EXIT_MAX; i++)
       {
         if (group->tg_exit[i].func.on == esp_thread_semphr_free)
           {
             break;
           }
       }
   
     if (i >= CONFIG_SCHED_EXIT_MAX)
       {
         sem = esp_semphr_create(1, 0);
         if (!sem)
           {
             wlerr("ERROR: Failed to create semaphore\n");
             return NULL;
           }
   
         ret = on_exit(esp_thread_semphr_free, sem);
         if (ret < 0)
           {
             wlerr("ERROR: Failed to bind semaphore\n");
             esp_semphr_delete(sem);
             return NULL;
           }
       }
     else
       {
         sem = group->tg_exit[i].arg;
       }
   
     return sem;
   }
   ```
