drxk_hard.c: In function 'hi_command.constprop':
drxk_hard.c:1016:5: warning: 'wait_cmd' may be used uninitialized in this function [-Wmaybe-uninitialized]
 1015 |   } while ((status < 0) && (retry_count < DRXK_MAX_RETRIES)
      |            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 1016 |     && (wait_cmd != 0));
      |     ^~~~~~~~~~~~~~~~~~

Just initialize wait_cmd to 0.
