mm: correct typo in MMAP_STATE() macro

[PATCH] mm: correct typo in MMAP_STATE() macro

Posted by Lorenzo Stoakes 2 days, 22 hours ago

We mistakenly refer to len rather than len_ here. The only existing caller
passes len to the len_ parameter so this has no impact on the code, but it
is obviously incorrect to do this, so fix it.
