[PATCH v2 2/9] drm/mediatek: fix OF sibling-node lookup

by Johan Hovold

Use the new of_get_compatible_child() helper to lookup the sibling instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (i.e. non-sibling) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the parent device node). While at it, also fix the related cec-node reference leak.

Backport e666d4e9ceec crypto: vmx - Use skcipher for ctr fallback

by Petr Vorel

Hi, I wonder, it it makes sense to backport commit e666d4e9ceec crypto: vmx - Use skcipher for ctr fallback to v 4.14 stable kernel. I'm using it in 4.12+. These commits (somehow similar) has been backported to 4.10.2: 5839f555fa57 crypto: vmx - Use skcipher for xts fallback c96d0a1c47ab crypto: vmx - Use skcipher for cbc fallback Kind regards, Petr

[PATCH 1/3] drm/i915: Handle incomplete Z_FINISH for compressed error states

by Chris Wilson

The final call to zlib_deflate(Z_FINISH) may require more output space to be allocated and so needs to re-invoked. Failure to do so in the current code leads to incomplete zlib streams (albeit intact due to the use of Z_SYNC_FLUSH) resulting in the occasional short object capture.

Hi Greg, This patch is not marked for 4.4-stable, but it's already in 4.9 and 4.14 stable. This is a trivial rename patch, but the naming would be more logical and makes backports easier. Please consider to apply this patch to 4.4-stable. -- SZ Lin (林上智)
