+Subject: remoteproc: Fix wrong rvring index computation
+
+From: Clement Leger <cleger@kalray.eu>
+
+commit 00a0eec59ddbb1ce966b19097d8a8d2f777e726a upstream.
+
+Index of rvring is computed using pointer arithmetic. However, since
+rvring->rvdev->vring is the base of the vring array, computation
+of rvring idx should be reversed. It previously lead to writing at negative
+indices in the resource table.

+Subject: ubifs: Fix ubifs_tnc_lookup() usage in do_kill_orphans()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8

+
+commit 4ab25ac8b2b5514151d5f91cf9514df08dd26938 upstream.
+
+Orphans are allowed to point to deleted inodes.
+So -ENOENT is not a fatal error.
