Hi Guix and Lars (as a known ROCm user and knowledgeable about these packages),

Attached is a patch to update our rocm packages to the new release, 5.6.0. Nothing too major here in terms of packaging updates, was able to get rid of some unneeded patches and did some style updates at the same time. I also did llvm-for-rocm together in one patch/commit this time since I think it makes the most sense to include it as it should match rocm-version as well. I tested everything build locally (x86_64 only) and Darktable OpenCL works with this.

One gotcha I hit I wanted to note for future reference: rocm-comgr had lld (linker from LLVM) as an input which had worked. Until you change the order of the inputs. I guess some collision/conflict with the llvm-for-rocm used to build the package. The errors for 5.6.0 I saw were unable to link to LLVM libraries. Everything works fine removing that input.

Thanks!
John
