I'm not applying this patch series.

Especially I dislike the second patch.

First problem in the second patch.  You're doing two things
at once.  You're adding function documentation and also adding
a NULL pointer check.

Second problem, the NULL pointer check is gratuitous.  Document
that the 'm' member has to be non-NULL and leave the check out.

Thanks.
