Applied to unstable/master. Quoting from the bug:

It does touch shared driver code. I have no idea how common it is to
access a BMC over I2C, though the Kconfig makes it sound like this is
non-standard. For SRU I'm a little concerned about bredth of testing for
something like this that changes some fundamentals about talking to
devices and just went into Linus' tree in the still-open merge window.
My feeling is that this should bake a little longer to see if any
regressions are reported before we SRU it.
