"net IPv6 : Fix broken IPv6 routing table after loopback down-up"
forgot to assign rt6_info to the inet6_ifaddr.
When disable the net device, the rt6_info which allocated
in init_loopback will not be destroied in __ipv6_ifa_notify.
This will trigger the waring message below

====================
here are there fixes for the v3.10 release cycle:
The first patch by Jonas Peterson and Olivier Sobrie fixes the reception of CAN
frames on Kvaser's "USBcan Pro" and "USBcan R" type hardware.
The last two patches by Olivier Sobrie (for esd_usb2) and me (for peak_usb)
change the memory handling for the USB messages from stack to kmalloc(), as
memory used for DMA should not be allocated on stack.

MAC addresses assigned by the PF to VFs were not kept in the PF driver

In the PF initialization, SRIOV is enabled before the PF is fully initialized.
This allows the kernel to probe the newly-exposed VFs before the PF is ready
to handle them (nested probes).
Have the probe method return the -EPROBE_DEFER value in this situation (instead
of the VF probe method retrying its initialization in a loop, and returning -EIO
on failure). When -EPROBE_DEFER is returned by the VF probe method, the kernel
itself will retry the probe after a suitable delay.

A couple of little bits and pieces, some delayed due to traveling.
1) A memory leak fix in the callback buffer.
2) Wrong exit path due to a return when it should have been a goto.
3) Bug in a mask value in ad4350
4) Reading the wrong value in raw to processed utility function.

The code uses
return foo;
goto err_type;
when instead the form should have been
ret = foo;
goto err_type;
Here this causes a useful iio_device_put to be skipped.

In summary, the symptom is intermittent key events lost after resume
on some machines with synaptics touchpad (seems this is synaptics _only_),
and key events loss is due to serio port reconnect after psmouse sync lost.
Removing psmouse and inserting it back during the suspend/resume process
is able to work around the issue, so the difference between psmouse_connect()
and psmouse_reconnect() is the key to the root cause of this problem.
After comparing the two different paths, synaptics driver has its own
implementation of synaptics_reconnect(), and the missing psmouse_probe()
seems significant, the patch below added psmouse_probe() to the reconnect
process, and has been verified many times that the issue could not be reliably
reproduced.
There are two PS/2 commands in psmouse_probe():
1. PSMOUSE_CMD_GETID
2. PSMOUSE_CMD_RESET_DIS
Only the PSMOUSE_CMD_GETID seems to be significant. The
PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying
several times. So we have only implemented this patch to issue
the PSMOUSE_CMD_GETID so far.

In intel_sdvo_get_lvds_modes() the wrong i2c adapter record is used
for DDC. Thus the code will always have to rely on a LVDS panel
mode supplied by VBT.
In most cases this succeeds, so this didn't get detected for quite
a while.
This regression seems to have been introduced in

The r8a7740 has two LCDC units and two sets of LCDC output signals. By
default LCDC0 is routed to the LCD0 signals, and LCDC1 to the LCD1
signals. However, LCDC1 can be routed to the LCD0 signals by setting bit
MSEL6 in MSEL3CR (the LCD0 signals are further pinmuxed the usual way).
This could be configured by duplicating the LCD0 pin groups for LCDC1.
However, this would unnecessarily complicate the LCD pin groups, as no
r8a7740 board supported in mainline use such a configuration. Hardcode
the MSEL3CR MSEL6 bit to 0 for now.
