This is where the declaration for struct device is along with other goodies like
get/put_device().

That is where struct file is declared.

This is where you get ida_simple_get() and ida_simple_remove() from.

This is where struct poll_table and poll_wait() comes from.

That one I agree with.

I started by this one and then I got carried away tested the other include...
You are right, I just don't follow her the first rule of the "submit checklist"
"If you use a facility then #include the file that defines/declares that
facility. Don’t depend on other header files pulling in ones that you use."
That said I just have a doubt for uapi/linux/rpmsg.h that will be include
by rpmsg.h[2], as these includes are part of the rpmsg framework API, should we
keep both, considering the rule as strict?

I red the last paragraph several times I can't understand what you are
trying to convey. Please rephrase, provide more context or detail exactly where
you think we have a problem.

There is no problem, just a question before sending an update.
As you mention the #include "rpmsg_internal.h" line can be removed, I plan to
send a patch V2 for this.
That's said before sending a new version I would like to propose to also remove
the #include <uapi/linux/rpmsg.h> line.
The rational to remove it is that include/rpmsg.h would already include
<uapi/linux/rpmsg.h> in 5.13 [2]. And looking at some frameworks (e.g I2C, TTY)
the drivers seem to include only the include/xxx.h and not the uapi/linux/xxx.h
in such case.
So my question is should I remove #include <uapi/linux/rpmsg.h> line? Or do
you prefer that i keep it?
Hope it is more clear... else please just forget my proposal, I wouldn't want
you to waste too much time for a point of detail.
Thanks,
Arnaud

Thanks for the clarifications, this is much much better.
Less changes is always preferred, so unless there is a clear guideline or a good
reason to make a change I would prefer to keep things the way they are.
