Hello Russell,
Thanks for the review. I do appreciate this. I'll send out v6 where I'll
have these fixed =)

I really don't know if there is any "sane" way to end up having the
devres data NULLed. I admit I looked an example on how others had
implemented the match. These checks were present in devm_clk_match
and devm_regmap_irq_chip_match so I assumed there is a way to end up
having NULL there. Thus I played safe. OTOH it seems that for example
devm_hwmon_match does omit these checks and I really don't see right
away why the dr->data would be NULL. So I'll remove the check.
