Subject: [PATCH v2] IB/cxgb3: remove cxio_dbg.c
cxio_dbg.c is uncompiled since commit 2b540355cd2f ("RDMA/cxgb3: cleanups")
10 years after, we could remove it.
Signed-off-by: Corentin Labbe <clabbe@...libre.com>
Acked-by: Steve Wise <swise@...ngridcomputing.com>
---
Changes since v1:
- Remove also all DEBUG code as suggested by Joe Perches
