From c098ce73c247a0e36d8a6b8cfdc7d05e4bc81bd0 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Wed, 16 Nov 2022 11:26:56 +0100 Subject: drm/exynos: remove FOLL_FORCE usage FOLL_FORCE is really only for ptrace access. As we unpin the pinned pages using unpin_user_pages_dirty_lock(true), the assumption is that all these pages are writable. FOLL_FORCE in this case seems to be a legacy leftover. Let's just remove it.
