Subject: [PATCH 1/3] drivers/gpu/drm/via: convert put_page() to put_user_page*()
Date:   Sun, 21 Jul 2019 21:30:10 -0700

From: John Hubbard <jhubbard@nvidia.com>

For pages that were retained via get_user_pages*(), release those pages
via the new put_user_page*() routines, instead of via put_page() or
release_pages().

This is part a tree-wide conversion, as described in commit fc1d8e7cca2d
("mm: introduce put_user_page*(), placeholder versions").
