Hi,
I was asked to send it for stable because this code
looks different in amd-staging-drm-next, see here.
https://gitlab.freedesktop.org/agd5f/linux/-/blob/amd-staging-drm-next/drivers/gpu/drm/amd/display/dc/dml/dcn32/display_mode_vba_util_32.c#L4661
I don't know what I am looking at, sorry.
Feel free to let me know if this is wrong, or if I
need to review some other guidelines I may have missed.
Please see the list of rules for stable patches:
https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
Does "remove code that does nothing" fit here?
Yep, it is a trivial fix which compilers should be able
to optimize, so no real benefit to the user. Sorry Greg!
José.
Hi Greg,
Sorry, I asked José to send it to stable because I realized the patch
listed in the fixes tag wasnt quite needed on stable. Patch from José
effectively removes it.
I hope that clears the context. But there is no impact whether you apply
José's patch or not, so we're good either way.
