Subject: video: fbdev: acornfb: remove free_unused_pages()
Patch series "mm: simplify free_highmem_page() and free_reserved_page()".
Let's simplify and unify free_highmem_page() and free_reserved_page().
This patch (of 2):
This function is never used and it is one of the last remaining user of
__free_reserved_page(). Let's just drop it.
