+static struct a500_ec *a500_ec_scratch;

If this is only used for power_off, please rename it. I've been told to
do so in my driver: https://lore.kernel.org/lkml/20200519104933.GX271301@dell/ (local)

I don't mind to rename the variable, but not sure whether it will be a
worthwhile change since _scratch is also a common naming scheme among
MFD drivers. Please see max77620_scratch for example, which I added
about a year ago.

If something is used once, it does not make it 'common'.

Not sure how this slipped my notice before, but I don't like it.

Ensure any global struct used for power_off only includes items
required for this purpose.  It's unfortunate this API requires a
global variable at all.

Okay! I'll change it in the v2, thanks!

Thierry Reding was working on the shutdown API which should replace the
global variables, unfortunately he doesn't have enough time to finish
that work yet.
