dim question: How to revert patches?

[Helge Deller]

Hello dri-devel & dim users,

I committed this patch to the drm-misc-next branch:

commit d6cd978f7e6b6f6895f8d0c4ce6e5d2c8e979afe
    video: fbdev: fbmem: fix pointer reference to null device field

then I noticed that it was fixed already in another branch which led to this error:

Merging drm-misc/drm-misc-next... dim:
dim: FAILURE: Could not merge drm-misc/drm-misc-next
dim: See the section "Resolving Conflicts when Rebuilding drm-tip"
dim: in the drm-tip.rst documentation for how to handle this situation.

I fixed it by reverting that patch above with this new commit in the drm-misc-next branch:

commit cabfa2bbe617ddf0a0cc4d01f72b584dae4939ad (HEAD -> drm-misc-next, drm-misc/for-linux-next, drm-misc/drm-misc-next)
Author: Helge Deller <deller at gmx.de>
    Revert "video: fbdev: fbmem: fix pointer reference to null device field"

My question (as "dim" newbie):
Was that the right solution?
Is there a possibility to drop those two patches from the drm-misc-next branch before it gets pushed upstream?

TIA,
Helge
