Hi all,

After merging the mediatek tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Caused by commit

   a92438c5a30a ("soc: mediatek: mtk-svs: Use bitfield access macros where possible")

I have used the mediatek tree from next-20220829 for today.

Thanks for the information. We were able to identify the issue (not really 
difficult) and I pushed a fix to my for-next tree. So we should be good by tomorrow.

Cheers,
Matthias
