4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>
This reverts commit e5d9ae0077a5cf336d298002959dc0c8dcfe7b89 which is
commit fe782affd0f440a4e60e2cc81b8f2eccb2923113 upstream
Rafael reports that this patch causes problems:
> -rc2 looks good. There is a problem on dragonboard during boot that was
> introduced in v4.14.71 that I didn't notice last week. We'll bisect it
> and report back later this week. dragonboard on the other branches (4.9,
> 4.18, mainline) looks fine.
As Dan pointed out, during validation, we have bisected this issue on
a dragonboard 410c (can't find root device) to the following commit
for v4.14:
[1ed3a9307230] rpmsg: core: add support to power domains for devices
There is an on-going discussion on "[PATCH] rpmsg: core: add support
to power domains for devices" about this patch having other
dependencies and breaking something else on v4.14 as well.
so drop it.
