Subject: [PATCH 18/34] fbdev/pvr2fb: convert put_page() to put_user_page*()

From: [email-masked]
Date: Thu, 1 Aug 2019 19:19:49 -0700

From: John Hubbard <[email-masked]>

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").
