Hi Christian,
this commit is causing a boot regression with v4.2-rcX on my Richland
APU (CHIP_ARUBA) based laptop. I didn't have time yet to track down
where exactly it is going wrong, but I bisected it down to this single
commit.
I don't have the VCE firmware installed on this system, so from a quick
look at the code I would expect it to drop out pretty early and just
leave the VCE unconfigured, but otherwise keep things working as before.
This is unfortunately not the case.
Maybe you can take a look at what's wrong here. We are already pretty
late in the release cycle and I'm unsure if I can find any more time to
look into the issue before the final release.
Thanks,
Lucas
