been resolved:\n\nnet/mlx5: fw_tracer, return NULL on create error\n\nTracer creation can fail by returning either NULL or ERR_PTR.\nThe return value is stored without a check on the device, and users\ntreat ERR_PTR and NULL the same way.\nThis also causes a crash in the core dump logic, which is missing the\nERR_PTR check and ends up dereferencing it, as shown in the trace below.\n\nSwitch tracer creation to return NULL on failure only, so callers only\nneed a single NULL check.\n\n  Internal error: Oops: 0000000096000006 [#1]  SMP\n  Modules linked in: mlx5_ib ib_uverbs ib_core ipv6
