The patch titled

From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx>
Subject: lib: bitmap: simplify bitmap_parselist
We want len to be the index of the first '\n', or the length of the string
if there is no newline. This is a good example of the usefulness of
strchrnul(). Use that instead, thus eliminating a branch and a call to
strlen().
