89259088c1 netfilter: nfnetlink_cttimeout: fetch timeouts for udplite and gre, too
syzbot was able to trigger the WARN in cttimeout_default_get() by
passing UDPLITE as l4protocol.  Alias UDPLITE to UDP, both use
same timeout values.

Furthermore, also fetch GRE timeouts.  GRE is a bit more complicated,
as it still can be a module and its netns_proto_gre struct layout isn't
visible outside of the gre module. Can't move timeouts around, it
appears conntrack sysctl unregister assumes net_generic() returns
nf_proto_net, so we get crash. Expose layout of netns_proto_gre instead.

A followup nf-next patch could make gre tracker be built-in as well
if needed, its not that large.

Last, make the WARN() mention the missing protocol value in case
anything else is missing.

2a31e4bd9a ipvs: call ip_vs_dst_notifier earlier than ipv6_dev_notf
ip_vs_dst_event is supposed to clean up all dst used in ipvs'
destinations when a net dev is going down. But it works only
when the dst's dev is the same as the dev from the event.

Now with the same priority but late registration,
ip_vs_dst_notifier is always called later than ipv6_dev_notf
where the dst's dev is set to lo for NETDEV_DOWN event.

As the dst's dev lo is not the same as the dev from the event
in ip_vs_dst_event, ip_vs_dst_notifier doesn't actually work.
Also as these dst have to wait for dest_trash_timer to clean
them up. It would cause some non-permanent kernel warnings:

  unregister_netdevice: waiting for br0 to become free. Usage count = 3

To fix it, call ip_vs_dst_notifier earlier than ipv6_dev_notf
by increasing its priority to ADDRCONF_NOTIFY_PRIORITY + 5.

Note that for ipv4 route fib_netdev_notifier doesn't set dst's
dev to lo in NETDEV_DOWN event, so this fix is only needed when
IP_VS_IPV6 is defined.

0bc3544a01 drm: rcar-du: Fix DU3 start/stop on M3-N
Group start/stop is controlled by the DRES and DEN bits of DSYSR0 for
the first group and DSYSR2 for the second group. On most DU instances,
this maps to the first CRTC of the group. On M3-N, however, DU2 doesn't
exist, but DSYSR2 does. There is no CRTC object there that maps to the
correct DSYSR register.

Commit 9144adc5e5 ("drm: rcar-du: Cache DSYSR value to ensure known
initial value") switched group start/stop from using group read/write
access to DSYSR to a CRTC-based API to cache the DSYSR value. While
doing so, it introduced a regression on M3-N by accessing DSYSR3 instead
of DSYSR2 to start/stop the second group.

To fix this, access the DSYSR register directly through group read/write
if the SoC is missing the first DU channel of the group. Keep using the
rcar_du_crtc_dsysr_clr_set() function otherwise, to retain the DSYSR
caching feature.

c4cfcf6f42 ALSA: hda/realtek - fix the pop noise on headphone for lenovo laptops
We have several Lenovo laptops with the codec alc285, when playing
sound via headphone, we can hear click/pop noise in the headphone,
if we let the headphone share the DAC of NID 0x2 with the speaker,
the noise disappears.

The Lenovo laptops here include P52, P72, X1 yoda2 and X1 carbon.

I have tried to set preferred_dacs and override_conn, but neither of
them worked. Thanks for Kailang, he told me to invalidate the NID 0x3
through override_wcaps.

275e4eb3f2 arm64: dts: renesas: Add all CPUs in cooling maps
Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.

Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.

Update cooling maps to include all devices affected by individual trip
points.

d92021f660 usb: dwc3: Add workaround for isoc start transfer failure
In DWC_usb31 version 1.70a-ea06 and prior, for highspeed and fullspeed
isochronous IN, BIT[15:14] of the 16-bit microframe number reported by
the XferNotReady event are invalid. The driver uses this number to
schedule the isochronous transfer and passes it to the START TRANSFER
command. Because this number is invalid, the command may fail. If
BIT[15:14] matches the internal 16-bit microframe, the START TRANSFER
command will pass and the transfer will start at the scheduled time, if
it is off by 1, the command will still pass, but the transfer will start
2 seconds in the future. For all other conditions, the START TRANSFER
command will fail with bus-expiry.

In order to workaround this issue, we can test for the correct
combination of BIT[15:14] by sending START TRANSFER commands with
different values of BIT[15:14]: 'b00, 'b01, 'b10, and 'b11. Each
combination is 2^14 uframe apart (or 2 seconds). 4 seconds into the
future will result in a bus-expiry status. As the result, within the 4
possible combinations for BIT[15:14], there will be 2 successful and 2
failure START COMMAND status. One of the 2 successful command status
will result in a 2-second delay start. The smaller BIT[15:14] value is
the correct combination.

Since there are only 4 outcomes and the results are ordered, we can
simply test 2 START TRANSFER commands with BIT[15:14] combinations 'b00
and 'b01 to deduce the smaller successful combination.

Let test0 = test status for combination 'b00 and test1 = test status for
'b01 of BIT[15:14]. The correct combination is as follow:

if test0 fails and test1 passes, BIT[15:14] is 'b01
if test0 fails and test1 fails, BIT[15:14] is 'b10
if test0 passes and test1 fails, BIT[15:14] is 'b11
if test0 passes and test1 passes, BIT[15:14] is 'b00

9aed8c08c8 usb: dwc2: gadget: Accept LPM token when TxFIFO is not empty
Set GLPMCFG_LPM_ACCEPT_CTRL_ISOC bit in GLPMCFG register
to accept LPM token during ISOC transfers when TxFIFO is
not empty.

- Added two definitions.
  	#define GLPMCFG_LPM_ACCEPT_CTRL_CONTROL        BIT(21)
  	#define GLPMCFG_LPM_ACCEPT_CTRL_ISOC   BIT(22)
  This patch uses GLPMCFG_LPM_ACCEPT_CTRL_ISOC.
  GLPMCFG_LPM_ACCEPT_CTRL_CONTROL is defined for further use.

- Added setting GLPMCFG_LPM_ACCEPT_CTRL_ISOC bit in GLPMCFG
  register in dwc2_gadget_init_lpm function.

ceb94bc52c usb: gadget: udc: renesas_usb3: add a safety connection way for forced_b_device
This patch adds a safety connection way for "forced_b_device" with
"workaround_for_vbus" like below:

< Example for R-Car E3 Ebisu >
 # modprobe <any usb gadget driver>
 # echo 1 > /sys/kernel/debug/ee020000.usb/b_device
 (connect a usb cable to host side.)
 # echo 2 > /sys/kernel/debug/ee020000.usb/b_device

Previous code should have connected a usb cable before the "b_device"
is set to 1 on the Ebisu board. However, if xHCI driver on the board
is probed, it causes some troubles:
 - Conflicts USB VBUS/signals between the board and another host.
 - "Cannot enable. Maybe the USB cable is bad?" might happen on
   both the board and another host with a usb hub.
 - Cannot enumerate a usb gadget correctly because an interruption
   of VBUS change happens unexpectedly.

Allow extcon device, found by name, to provide DR status for USB.
This is needed, for example, in case of Intel Merrifield platform,
where the Intel Basin Cove PMIC provides an extcon device to communicate
the detected role.

Note, that the "linux,extcon-name" property name is only for kernel
internal use by X86/ACPI platform code and as such is not documented
in the device tree bindings.

To dump internal LSP and endpoint state debug registers, we must write
to GDBGLSPMUX register. This patch correctly dump LSP and endpoint
states from the debug registers.

If the controller is in device mode, all LSP and endpoint state
registers will be dumped via the debugfs attribute "lsp_dump". In host
mode, the user has to write the LSP number to "lsp_dump" to dump a
specific LSP selection.
