Convert `to_gbphy_dev` and `to_gbphy_driver` macros into a
static inline functions.

it is not great to have macro that use `container_of` macro,
because from looking at the definition one cannot tell what type
it applies to.

One can get the same benefit from an efficiency point of view
by making an inline function.

You have made the patch against your previous patch that added a newline
here.  It should be against Greg's tree.

julia
you mean I should remove this newline, right?
You should apply your change to the state of Greg's tree, not the state
after your patch.

Assuming that you have committed both the patch adding the new line and
the patch changing the macro to a function, and have made no other
changes, you can do git rebase -i HEAD~2 and the put a d at the beginning
of the line related to the patch adding the newline.

you mean drop this patch "staging: greybus: remove unnecessary blank line"?
No, the one that removes the blank line looks fine.

At some point, you added a blank line below the two structure definitions.
That blank line is not in Greg's tree, so you shoulsn't send a patch that
assumes that it is there.


I'm sorry I mean this patch "staging: greybus: add blank line after struct", Julia I understood the issue

but I am confused about how to fix it, should I drop the patch that added the newline? then what should I do?

and version that I have submitted, should I do anything about it as you said it is wrong solution?

If you have made
more changes, you can adapt the HEAD~ part accordingly.
