+Subject: drm/panel: simple: Add missing panel_simple_unprepare() calls
+
+From: Jonathan Liu <net147@gmail.com>
+
+commit f3621a8eb59a913612c8e6e37d81f16b649f8b6c upstream.
+
+During panel removal or system shutdown panel_simple_disable() is called
+which disables the panel backlight but the panel is still powered due to
+missing calls to panel_simple_unprepare().
+
+Fixes: d02fd93e2cd8 ("drm/panel: simple - Disable panel on shutdown")

+Subject: NFS: revalidate "." etc correctly on "open".
+
+From: NeilBrown <neilb@suse.com>
+
+commit b688741cb06695312f18b730653d6611e1bad28d upstream.
+
+For correct close-to-open semantics, NFS must validate
+the change attribute of a directory (or file) on open.
+
+Since commit ecf3d1f1aa74 ("vfs: kill FS_REVAL_DOT by adding a
+d_weak_revalidate dentry op"), open() of "." or a path ending ".." is
+not revalidated reliably (except when that direct is a mount point).
+
+Prior to that commit, "." was revalidated using nfs_lookup_revalidate()
+which checks the LOOKUP_OPEN flag and forces revalidation if the flag is
+set.
+Since that commit, nfs_weak_revalidate() is used for NFSv3 (which
+ignores the flags) and nothing is used for NFSv4.
+
+This is fixed by using nfs_lookup_verify_inode() in
+nfs_weak_revalidate().  This does the revalidation exactly when needed.
+Also, add a definition of .d_weak_revalidate for NFSv4.
+
+The incorrect behavior is easily demonstrated by running "echo *" in
+some non-mountpoint NFS directory while watching network traffic.
+Without this patch, "echo *" sometimes doesn't produce any traffic.
+With the patch it always does.
+
+Fixes: ecf3d1f1aa74 ("vfs: kill FS_REVAL_DOT by adding a d_weak_revalidate dentry op")
