From 27bc773aa69cf9aa03020a9d87abbcf06d4af1c2 Mon Sep 17 00:00:00 2001 From: Jordan Crouse Date: Mon, 3 Dec 2018 15:47:14 -0700 Subject: drm/msm/dpu: Remove dpu_dbg The functions in dpu_dbg.c aren't used. The two main dump functions fail after a lookup from dpu_dbg_base.reg_base_list which turns out to never be populated and once those are removed the rest of the file doesn't make any sense. v3: No changes v2: Moved some unrelated changes to another patch Reviewed-by: Sean Paul Signed-off-by: Jordan Crouse Signed-off-by: Sean Paul Signed-off-by: Rob Clark --- drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.h | 103 -------------------------------- 1 file changed, 103 deletions(-) delete mode 100644 drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.h (limited to 'drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.h') diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.h b/drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.h deleted file mode 100644 index 1e6fa945f98b..000000000000 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.h +++ /dev/null @@ -1,103 +0,0 @@ -/* Copyright (c) 2016-2018, The Linux Foundation.
