+Subject: ALSA: hda/conexant - Fix audio routing for HP EliteOne 1000 G2
+
+From: Vasiliy Kovalev <kovalev@altlinux.org>
+
+commit 9988844c457f6f17fb2e75aa000b6c3b1b673bb9 upstream.
+
+There is a problem with simultaneous audio output to headphones and
+speakers, and when headphones are turned off, the speakers also turn
+off and do not turn them on.
+
+However, it was found that if you boot linux immediately after windows,
+there are no such problems. When comparing alsa-info, the only difference
+is the different configuration of Node 0x1d:
+
+working conf. (windows): Pin-ctls: 0x80: HP
+not working (linux): Pin-ctls: 0xc0: OUT HP
+
+This patch disable the AC_PINCTL_OUT_EN bit of Node 0x1d and fixes the
+described problem.

+Subject: btrfs: fix uninitialized pointer free in add_inode_ref()
+
+From: Roi Martin <jroi.martin@gmail.com>
+
+commit 66691c6e2f18d2aa4b22ffb624b9bdc97e9979e4 upstream.
+
+The add_inode_ref() function does not initialize the "name" struct when
+it is declared. If any of the following calls to "read_one_inode()
+returns NULL,
+
+ dir = read_one_inode(root, parent_objectid);
+ if (!dir) {
+ ret = -ENOENT;
+ goto out;
+ }
+
+ inode = read_one_inode(root, inode_objectid);
+ if (!inode) {
+ ret = -EIO;
+ goto out;
+ }
+
+then "name.name" would be freed on "out" before being initialized.
+
+out:
+ ...
+ kfree(name.name);
+
+This issue was reported by Coverity with CID 1526744.

+Subject: btrfs: fix uninitialized pointer free on read_alloc_one_name() error
+
+From: Roi Martin <jroi.martin@gmail.com>
+
+commit 2ab5e243c2266c841e0f6904fad1514b18eaf510 upstream.
+
+The function read_alloc_one_name() does not initialize the name field of
+the passed fscrypt_str struct if kmalloc fails to allocate the
+corresponding buffer. Thus, it is not guaranteed that
+fscrypt_str.name is initialized when freeing it.
+
+This is a follow-up to the linked patch that fixes the remaining
+instances of the bug introduced by commit e43eec81c516 ("btrfs: use
+struct qstr instead of name and namelen pairs").

+
+From: Namjae Jeon <linkinjeon@kernel.org>
+
+commit 7aa8804c0b67b3cb263a472d17f2cb50d7f1a930 upstream.
+
+There is racy issue between smb2 session log off and smb2 session setup.
+It will cause user-after-free from session log off.
+This add session_lock when setting SMB2_SESSION_EXPIRED and referece
+count to session struct not to free session while it is being used.

+That's because 'subflow' is used just after 'mptcp_close_ssk(subflow)',
+which will initiate the release of its memory. Even if it is very likely
+the release and the re-utilisation will be done later on, it is of
+course better to avoid any issues and read the content of 'subflow'
+before closing it.
