Re: [BISECTED REGRESSION] v4.8-rc: DT/OCTEON driver probing broken

Lo! Kefeng, below report made it to the list of regression for 4.8, but
afaics nothing happened after the initial report. Is there maybe some
reason why it shouldn't be on the list of regressions at all? Or was the
problem discussed elsewhere? Or is it even fixed already? I noticed
https://git.kernel.org/torvalds/c/fc520f8b4f (of/platform: disable the
of_platform_default_populate_init() for all the ppc board), but that
change is PPC specific.

Ciao, Thorsten
