If the timer callback (command_timer_fn) is already\nrunning when lbtf_free_cmd_buffer() frees the command array, the\ncallback dereferences priv-\u003ecur_cmd-\u003ecmdbuf which points to freed\nmemory.\n\nSwap the order so that timer_delete_sync() runs first, ensuring any\nin-flight callback has completed before the command buffers are freed.",
