[PATCH net-next] net/mlx5: HWS, check the correct variable in hws_send_ring_alloc_sq()
From: Dan Carpenter
Date: Sat Sep 14 2024 - 05:59:34 EST
There is a copy and paste bug so this code checks "sq->dep_wqe" where
"sq->wr_priv" was intended. It could result in a NULL pointer
dereference.
Fixes: 2ca62599aa0b ("net/mlx5: HWS, added send engine and context handling")
