I added 3 patches moving to wrappers before refactoring, and one other patch is unreviewed (07) but the main comment was wanting the wrappers. Jani if you are happy with the final 4 patches can you land this series, I don't think I have drm-intel commit rights. v1: This is orthogonal to my display ptr refactoring and should probably be applied first. The display funcs vtable was a bit of mess, lots of intermixing of internal display functionality and interfaces to watermarks/irqs. It's also considered not great security practice to leave writeable function pointers around for exploits to get into. This series attempts to address both problems, first there are a few cleanups, then it splits the function table into multiple pieces. Some of the splits might be bikesheds but I think we should apply first and merge things later if there is good reason. The second half converts all the vtables to static const structs, I've used macros in some of them to make it less messy, the cdclk one is probably the worst one. v2: Added some patches adding wrappers around things before refactoring them as suggested by Jani. Fixed up all struct names as suggested by Jani. Added s-o-b lines Added commit msgs. Dave.
