Your comment was in https://patchwork.freedesktop.org/patch/345025/?series=68028&rev=14,
however I seem to have wrongly interpreted it. I think my motivation to switch
to plane based iteration was because its way easier to call skl_plane_wm_level
function then, because it takes plane itself as a parameter, also as it had already
an id, thought it is also better that way, rather than keeping one more variable
instead. Whatever.. I'm fine with both, that is not critical anyways.

When did I say that? Can't find a previous review of this patch.
Anywyas, that change seems to cause a lot of needless noise into the
patch, and atm I can't see why we'd require it.

nit: I'd put the crtc_state as the first parameter as that's the thing
we're operating on. The other stuff just specifies which piece we want

When did I say that? Can't find a previous review of this patch.
Anywyas, that change seems to cause a lot of needless noise into the
patch, and atm I can't see why we'd require it.
