An unintended post-condition of probe() is that the watchdog is
disabled. This behaviour was introduced by an unnecessary write to the
control register to configure the hardware based on the devicetree. The
write is unnecessary because the cached control value that is
manipulated by the code parsing the devicetree is eventually written by
aspeed_wdt_enable(), which is when we care how the control register
should be configured.
Remove the write to restore expected behaviour.

This patch exposes the option to dynamic allocates a UAR, this
functionality will be used in downstream patch in this series as
part of QP creation.
Specifically, the user space driver asks for a UAR allocation in a given
page index, upon success this UAR and its bfregs can be used as part of
QP creation by the user space driver.
To enable allocating more than 256 UARs the page index is encoded in an
extra one byte just after the command byte.

This patch extends the alloc context flow to be prepared for working
with dynamic UAR allocations.
Currently upon alloc context there is some fix size of UARs that are
allocated (named 'static allocation') and there is no option to user
application to ask for more or control which UAR will be used by which
QP.
In this patch the driver prepares its data structures to manage both the
static and the dynamic allocations and let the user driver knows about
the max value of dynamic blue-flame registers that are allowed.
Downstream patches from this series will enable the dynamic allocation
and the association as part of QP creation.

- DMX_REQBUFS: Request kernel to allocate buffers which count and size
are dedicated by user.
- DMX_QUERYBUF: Get the buffer information like a memory offset which
will mmap() and be shared with user-space.
- DMX_EXPBUF: Just for testing whether buffer-exporting success or not.
- DMX_QBUF: Pass the buffer to kernel-space.
- DMX_DQBUF: Get back the buffer which may contain TS data.
Originally developed by: Junghak Sung <jh1009.sung@samsung.com>, as
seen at:
https://patchwork.linuxtv.org/patch/31613/https://patchwork.kernel.org/patch/7334301/
The original patch was written before merging VB2-core functionalities
upstream. When such series was added, several adjustments were made,
fixing some issues with V4L2, causing the original patch to be
non-trivially rebased.
After rebased, a few bugs in the patch were fixed. The patch was
also enhanced it and polling functionality got added.
The main changes over the original patch are:
dvb_vb2_fill_buffer():
- Set the size of the outgoing buffer after while loop using
vb2_set_plane_payload;
- Added NULL check for source buffer as per normal convention
of demux driver, this is called twice, first time with valid
buffer second time with NULL pointer, if its not handled,
it will result in crash
- Restricted spinlock for only list_* operations
dvb_vb2_init():
- Restricted q->io_modes to only VB2_MMAP as its the only
supported mode
dvb_vb2_release():
- Replaced the && in if condiion with &, because otherwise
it was always getting satisfied.
dvb_vb2_stream_off():
- Added list_del code for enqueud buffers upon stream off
dvb_vb2_poll():
- Added this new function in order to support polling
dvb_demux_poll() and dvb_dvr_poll()
- dvb_vb2_poll() is now called from these functions
- Ported this patch and latest videobuf2 to lower kernel versions and
tested auto scan.

We're seeing a lot of bogus backlight interfaces on newer machines without
a LCD such as desktops, servers and HDMI sticks. This causes userspace to
show a non-functional brightness slider in e.g. the GNOME3 system menu,
which is undesirable. And, in general, we should simply just not register
a non functional backlight interface.
Checking the LCD flag causes the bogus acpi_video backlight interfaces to
go away (on the machines this was tested on).
This change sets the lcd_only option by default on any machines which
are Win8-ready, to fix this.
This is not entirely without a risk of regressions, but video_detect.c
already prefers native-backlight interfaces over the acpi_video one
on Win8-ready machines, calling acpi_video_unregister_backlight() as soon
as a native interface shows up. This is done because the ACPI backlight
interface often is broken on Win8-ready machines, because win8 does not
seem to actually use it.
So in practice we already end up not registering the ACPI backlight
interface on (most) Win8-ready machines with a LCD panel, thus this
change does not change anything for (most) machines with a LCD panel
and on machines without a LCD panel we actually don't want to register
any backlight interfaces.
This has been tested on the following machines and fixes a bogus backlight
interface showing up there:
- Desktop with an Asrock B150M Pro4S/D3 m.b. using i5-6500 builtin gfx
- Intel Compute Stick STK1AW32SC
- Meegopad T08 HDMI stick
Bogus backlight interfaces have also been reported on:
- Desktop with Asus H87I-Plus m.b.
- Desktop with ASRock B75M-ITX m.b.
- Desktop with Gigabyte Z87-D3HP m.b.
- Dell PowerEdge T20 desktop

Ethernet representors have a need to store data which is applicable
only for them. Create a priv void pointer in struct mlx5_eswitch_rep
and move mlx5e to store the relevant data there. As part of this change
we also initialize rep_if in mlx5e_rep_register_vf_vports() as otherwise the
E-Switch code will copy a priv value which is garbage.
We also rename mlx5_eswitch_get_uplink_netdev() to
mlx5_eswitch_get_uplink_priv() and make it return void *.
This way E-Switch code doesn't need to deal with net devices and
we leave the task of getting it to mlx5e.
