I think it was something like the following, but I don't remember
off hand without re-running the build that caused it and booting it
again.

twl6040 0-004b: Unable to sync registers 0xc-0xd. -121

I got that while trying my hibernate test (which fails due to no swap)
but it shouldn't cause any other errors:

CPU1: shutdown
PM: Creating hibernation image:

PM: Normal pages needed: 9337 + 1024, available pages: 54137

That's probably not regmap's fault, but something else.  I guess TIers
need to dig into that one.
