net: fec: fix build error in fec driver

2018-04-10T07:03:51+00:00

commit f4d8124a4ade232cae1161a6aca86e0c0a1fa4f6 which is commit 
a069215cf5985f3aa1bba550264907d6bd05c5f7 upstream caused a build error
in the driver, as the pm functions were not included properly.  So fix
that by including the needed .h file.

Revert "PCI/MSI: Stop disabling MSI/MSI-X in pci_device_shutdown()"

2018-04-08T09:49:49+00:00

This reverts commit 058645e2f0647c85f2bfd577771546d198739fd2 which was
commit fda78d7a0ead144f4b2cdb582dcba47911f4952c upstream.

The dependancy tree is just too messy here, just drop it from this
kernel as it's not really needed here.

md/raid10: reset the 'first' at the end of loop

2018-04-08T09:49:49+00:00

commit 6f287ca6046edd34ed83aafb7f9033c9c2e809e2 upstream.

We need to set "first = 0' at the end of rdev_for_each
loop, so we can get the array's min_offset_diff correctly
otherwise min_offset_diff just means the last rdev's
offset diff.

[only the first chunk, due to b506335e5d2b ("md/raid10: skip spare disk as
'first' disk") being already applied - gregkh]

vt: change SGR 21 to follow the standards

2018-04-08T09:49:48+00:00

commit 65d9982d7e523a1a8e7c9af012da0d166f72fc56 upstream.

ECMA-48 [1] (aka ISO 6429) has defined SGR 21 as "doubly underlined"
since at least March 1984.  The Linux kernel has treated it as SGR 22
"normal intensity" since it was added in Linux-0.96b in June 1992.
Before that, it was simply ignored.  Other terminal emulators have
either ignored it, or treat it as double underline now.  xterm for
example added support in its 304 release (May 2014) [2] where it was
previously ignoring it.

Changing this behavior shouldn't be an issue:
- It isn't a named capability in ncurses's terminfo database, so no
  script is using libtinfo/libcurses to look this up, or using tput
  to query & output the right sequence.
- Any script assuming SGR 21 will reset intensity in all terminals
  already do not work correctly on non-Linux VTs (including running
  under screen/tmux/etc...).
- If someone has written a script that only runs in the Linux VT, and
  they're using SGR 21 (instead of SGR 22), the output should still
  be readable.

imo it's important to change this as the Linux VT's non-conformance
is sometimes used as an argument for other terminal emulators to not
implement SGR 21 at all, or do so incorrectly.

Input: i8042 - enable MUX on Sony VAIO VGN-CS series to fix touchpad

2018-04-08T09:49:48+00:00

commit 04bb1719c4de94700056241d4c0fe3c1413f5aff upstream.

The touch sensor buttons on Sony VAIO VGN-CS series laptops (e.g.
VGN-CS31S) are a separate PS/2 device. As the MUX is disabled for all
VAIO machines by the nomux blacklist, the data from touch sensor
buttons and touchpad are combined. The protocol used by the buttons is
probably similar to the touchpad protocol (both are Synaptics) so both
devices get enabled. The controller combines the data, creating a mess
which results in random button clicks, touchpad stopping working and
lost sync error messages:
psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4
psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1
psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1
psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1
psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1
psmouse serio1: issuing reconnect request

Add a new i8042_dmi_forcemux_table whitelist with VGN-CS.
With MUX enabled, touch sensor buttons are detected as separate device
(and left disabled as there's currently no driver), fixing all touchpad
problems.

Input: i8042 - add Lenovo ThinkPad L460 to i8042 reset list

2018-04-08T09:49:48+00:00

commit b56af54ac78c54a519d82813836f305d7f76ef27 upstream.

Reset i8042 before probing because of insufficient BIOS initialisation of
the i8042 serial controller. This makes Synaptics touchpad detection
possible. Without resetting the Synaptics touchpad is not detected because
there are always NACK messages from AUX port.

media: usbtv: prevent double free in error case

2018-04-08T09:49:48+00:00

commit 50e7044535537b2a54c7ab798cd34c7f6d900bd2 upstream.

Quoting the original report:

It looks like there is a double-free vulnerability in Linux usbtv driver
on an error path of usbtv_probe function. When audio registration fails,
usbtv_video_free function ends up freeing usbtv data structure, which
gets freed the second time under usbtv_video_fail label.

usbtv_audio_fail:

        usbtv_video_free(usbtv); =>

           v4l2_device_put(&usbtv->v4l2_dev);

              => v4l2_device_put

                  => kref_put

                      => v4l2_device_release

  => usbtv_release (CALLBACK)

                             => kfree(usbtv) (1st time)

usbtv_video_fail:

        usb_set_intfdata(intf, NULL);

        usb_put_dev(usbtv->udev);

        kfree(usbtv); (2nd time)

So, as we have refcounting, use it

mei: remove dev_err message on an unsupported ioctl

2018-04-08T09:49:48+00:00

commit bb0829a741792b56c908d7745bc0b2b540293bcc upstream.

Currently the driver spams the kernel log on unsupported ioctls which is
unnecessary as the ioctl returns -ENOIOCTLCMD to indicate this anyway.
I suspect this was originally for debugging purposes but it really is not
required so remove it.
