[PATCH 4/4] mfd: db8500 stop passing around platform data

[PATCH 4/4] mfd: db8500 stop passing around platform data

[Arnd Bergmann]

Except for the constant DB8500_PRCMU_FW_VERSION_OFFSET number, nothing
is ever passed through the platform data and used in a driver, so we
can simply stop passing it around.

Do you think it's relevant for Lee to take this or do you want to
have it in ARM SoC together with the other cleanups (that I
haven't had time to look at...)?

In the latter case I need an ACK from Lee to apply it for a pull
request to ARM SoC.

The functionality it pertains to is out-of-tree but if we want to
reintroduce it, it should happen through DT anyway.

Yours,
Linus Walleij

I think most of the changes are in mfd, so it would be appropriate
for Lee to take them all, but I could also put them into arm-soc
if he prefers.

Up to you.  If you want a pull-request, I can provide you with one.
If you are happy to 'risk it', I'm good with that too.
