[PATCH] mm: Remove 'return;' at the end of void cma_activate_area()
Posted by winterver 1 week ago
From: Jiale Yang <295107659@qq.com>

Remove 'return;' at the end of void cma_activate_area(). It's a void
function, so an ending return statement is unnecessary.

Looks good to me.  But, seems a same change[1] from Pintu Kumar has already
merged into mm-unstable?
