[PATCH net v2] docs: netdev: document guidance on cleanup patches

[Simon Horman <horms@kernel.org>]

The purpose of this section is to document what is the current practice
regarding clean-up patches which address checkpatch warnings and similar
problems. I feel there is a value in having this documented so others
can easily refer to it.

Clearly this topic is subjective. And to some extent the current
practice discourages a wider range of patches than is described here.
But I feel it is best to start somewhere, with the most well established
part of the current practice.

I did think this was already documented. And perhaps it is.
But I was unable to find it after a quick search.

+Clean-up patches
+~~~~~~~~~~~~~~~~
+
+Netdev discourages patches which perform simple clean-ups, which are not in
+the context of other work. For example:
+
+* Addressing ``checkpatch.pl`` warnings
+* Addressing :ref:`Local variable ordering<rcs>` issues
+* Conversions to device-managed APIs (``devm_`` helpers)
+
+This is because it is felt that the churn that such changes produce comes
+at a greater cost than the value of such clean-ups.
+
+Conversely, spelling and grammar fixes are not discouraged.
