Subject: mm/damon/dbgfs: use kmalloc for allocating only one element
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b2d4c646d5a15c1854e09898a374983167e53e0e;p=linux.git

mm/damon/dbgfs: use kmalloc for allocating only one element

Use kmalloc(...) rather than kmalloc_array(1, ...) because the number of
elements we are specifying in this case is 1, kmalloc would accomplish the
same thing and we can simplify.
