Sorry, those 2 changes really should have been in a separate commit.
I've put the 2 get -> get_sync() changed in their own commit now
with the following commit-msg:

"""
extcon: arizona: Always use pm_runtime_get_sync() when we need the device to be awake

Before this commit the extcon-arizona code was mixing pm_runtime_get()
and pm_runtime_get_sync() in different places. In all cases where
either function is called we make use of the device immediately
afterwards. This means that we should always use pm_runtime_get_sync().
"""

> along with moving disable()?
The enable / disable calls are not moved, they are removed.

Here is a new commit msg which hopefully explains this better
which I plan to use for v3:

"""
Drivers for MFD child-devices such as the arizona codec drivers
and the arizona-extcon driver can choose to either make
runtime_pm_get/_put calls on their own child-device, which will
then be propagated to their parent; or they can make them directly
on their MFD parent-device.

The arizona-extcon code was using runtime_pm_get/_put calls on
its own child-device where as the codec drivers are using
runtime_pm_get/_put calls on their parent.

The arizona-extcon MFD cell/child-device has been removed and this
commit is part of refactoring the arizona-extcon code into a library
to be used directly from the codec drivers.

Specifically this commit moves the code over to make
runtime_pm_get/_put calls on the parent device (on arizona->dev)
bringing the code inline with how the codec drivers do this.

Note this also removes the pm_runtime_enable/_disable calls
as pm_runtime support has already been enabled on the parent-device
by the arizona MFD driver.
