[PATCH 1/3] drivers/gpu/drm/via: convert put_page() to put_user_page*()

From: john . hubbard
Date: Mon Jul 22 2019 - 00:30:25 EST


From: John Hubbard <jhubbard@xxxxxxxxxx>

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").
