129fc67785 mfd: axp20x: Add USB power supply mfd cell to AXP813
The AXP813 has a VBUS power input. Now that the axp20x_usb_power driver
supports this variant, we can add an mfd cell for it to use it.

48171d0ea7 mfd: twl6040: Fix device init errors for ACCCTL register
I noticed that we can get a -EREMOTEIO errors on at least omap4 duovero:

twl6040 0-004b: Failed to write 2d = 19: -121

And then any following register access will produce errors.

There 2d offset above is register ACCCTL that gets written on twl6040
powerup. With error checking added to the related regcache_sync() call,
the -EREMOTEIO error is reproducable on twl6040 powerup at least
duovero.

To fix the error, we need to wait until twl6040 is accessible after the
powerup. Based on tests on omap4 duovero, we need to wait over 8ms after
powerup before register write will complete without failures. Let's also
make sure we warn about possible errors too.

Note that we have twl6040_patch[] reg_sequence with the ACCCTL register
configuration and regcache_sync() will write the new value to ACCCTL.

fbcde197e1 gfs2: Fix error path kobject memory leak
If a call to kobject_init_and_add() fails we must call kobject_put()
otherwise we leak memory.

Function gfs2_sys_fs_add always calls kobject_init_and_add() which
always calls kobject_init().

It is safe to leave object destruction up to the kobject release
function and never free it manually.

Remove call to kfree() and always call kobject_put() in the error path.

a9b8a2b39c bonding: fix arp_validate toggling in active-backup mode
There's currently a problem with toggling arp_validate on and off with an
active-backup bond. At the moment, you can start up a bond, like so:

modprobe bonding mode=1 arp_interval=100 arp_validate=0 arp_ip_targets=192.168.1.1
ip link set bond0 down
echo "ens4f0" > /sys/class/net/bond0/bonding/slaves
echo "ens4f1" > /sys/class/net/bond0/bonding/slaves
ip link set bond0 up
ip addr add 192.168.1.2/24 dev bond0

Pings to 192.168.1.1 work just fine. Now turn on arp_validate:

echo 1 > /sys/class/net/bond0/bonding/arp_validate

Pings to 192.168.1.1 continue to work just fine. Now when you go to turn
arp_validate off again, the link falls flat on it's face:

echo 0 > /sys/class/net/bond0/bonding/arp_validate
dmesg
...
[133191.911987] bond0: Setting arp_validate to none (0)
[133194.257793] bond0: bond_should_notify_peers: slave ens4f0
[133194.258031] bond0: link status definitely down for interface ens4f0, disabling it
[133194.259000] bond0: making interface ens4f1 the new active one
[133197.330130] bond0: link status definitely down for interface ens4f1, disabling it
[133197.331191] bond0: now running without any active interface!

The problem lies in bond_options.c, where passing in arp_validate=0
results in bond->recv_probe getting set to NULL. This flies directly in
the face of commit 3fe68df97c, which says we need to set recv_probe =
bond_arp_recv, even if we're not using arp_validate. Said commit fixed
this in bond_option_arp_interval_set, but missed that we can get to that
same state in bond_option_arp_validate_set as well.

One solution would be to universally set recv_probe = bond_arp_recv here
as well, but I don't think bond_option_arp_validate_set has any business
touching recv_probe at all, and that should be left to the arp_interval
code, so we can just make things much tidier here.

After calling phy_select_page() and until calling phy_restore_page(),
the mutex 'mdio_lock' is already locked, so the driver should use
non-locked version of phy functions. Or there will be a deadlock with

5afcd14cfc net: seeq: fix crash caused by not set dev.parent
The old MIPS implementation of dma_cache_sync() didn't use the dev argument,
but commit c9eb6172c3 ("dma-mapping: turn dma_cache_sync into a
dma_map_ops method") changed that, so we now need to set dev.parent.

Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Postpone chain policy update to drop after transaction is complete,
   from Florian Westphal.

2) Add entry to flowtable after confirmation to fix UDP flows with
   packets going in one single direction.

3) Reference count leak in dst object, from Taehee Yoo.

4) Check for TTL field in flowtable datapath, from Taehee Yoo.

5) Fix h323 conntrack helper due to incorrect boundary check,
   from Jakub Jankowski.

6) Fix incorrect rcu dereference when fetching basechain stats,
   from Florian Westphal.

7) Missing error check when adding new entries to flowtable,
   from Taehee Yoo.

8) Use version field in nfnetlink message to honor the nfgen_family
   field, from Kristian Evensen.

9) Remove incorrect configuration check for CONFIG_NF_CONNTRACK_IPV6,
   from Subash Abhinov Kasiviswanathan.

10) Prevent dying entries from being added to the flowtable,
    from Taehee Yoo.

11) Don't hit WARN_ON() with malformed blob in ebtables with
    trailing data after last rule, reported by syzbot, patch
    from Florian Westphal.

12) Remove NFT_CT_TIMEOUT enumeration, never used in the kernel
    code.

13) Fix incorrect definition for NFT_LOGLEVEL_MAX, from Florian
    Westphal.

This batch comes with a conflict that can be fixed with this patch:

That replaces the unused NFT_CT_TIMEOUT definition by NFT_CT_ID. If you prefer,
I can also solve this conflict here, just let me know.
