nit: There is an odd mix of uint64_t and u64 (and alike) in the MSM code :) The uint64_t variant shouldn't be used by kernel code in general and checkpatch should want about it.
one of many things that I disagree with checkpatch about ;-)
I prefer standard types to custom ones. I _kinda_ get the argument in case of uapi (but IMHO that doesn't apply to how drm uapi headers are used)
I'd understand if it was all either uint64_t or u64, but the mix.. hm.
