[PATCH v2 0/9] EEH refactoring 1

[Sam Bobroff]

Hello everyone,

Here is a set of some small, mostly idempotent, changes to improve
maintainability in some of the EEH code, primarily in eeh_driver.c.

I've kept them all small to aid review but perhaps they should be squashed down
before being applied.

Cheers,
Sam.
