It would be good to have those warnings included in the changelog as well.

As in, copy-pasting the compiler's output? Isn't the change explicit enough?

If you just do 'git log' you can't see the change itself and that's where
the changelog should help. If I see some warnings when I build the kernel,
the first thing I usually do is to check 'git log' against linux-next and
see if someone has already fixed that warning (grepping the warning message
from changelog).

Ah, I can see several examples of what you mention indeed. Will add 
these and send a v2.

[PATCH v2] gpiolib: add missing declarations

[Alexandre Courbot]

Add declaration of 'struct of_phandle_args' to avoid the following
warning:

  In file included from arch/arm/mach-tegra/board-paz00.c:21:0:
  include/linux/gpio/driver.h:102:17: warning: 'struct of_phandle_args' declared inside parameter list
  include/linux/gpio/driver.h:102:17: warning: its scope is only this definition or declaration, which is probably not what you want

Also proactively add other definitions/includes that could be missing
in other contexts.
