a86854d0c5 treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

 - remove of atomisp driver from staging, as nobody would have time to
   dedicate huge efforts to fix all the problems there. Also, we have a
   feeling that the driver may not even run the way it is.

 - move Zoran driver to staging, in order to be either fixed to use VB2
   and the proper media kAPIs or to be removed

 - remove videobuf-dvb driver, with is unused for a while

 - some V4L2 documentation fixes/improvements

 - new sensor drivers: imx258 and ov7251

 - a new driver was added to allow using I2C transparent drivers

 - several improvements at the ddbridge driver

 - several improvements at the ISDB pt1 driver, making it more coherent
   with the DVB framework

 - added a new platform driver for MIPI CSI-2 RX: cadence

 - now, all media drivers can be compiled on x86 with COMPILE_TEST

 - almost all media drivers now build on non-x86 architectures with
   COMPILE_TEST

 - lots of other random stuff: cleanups, support for new board models,
   bug fixes, etc

 - Fixes for possible races in ALSA timer resolution accesses
 - TLV offset definitions in uapi
 
 ASoC:
 - Many fixes for the topology stuff, including fixes for v4 ABI
   compatibility
 - Lots of cleanups / quirks for Intel platforms based on Realtek
   CODECs
 - Continued componentization works, removing legacy CODEC stuff
 - Conversion of OMAP DMA to the new, more standard SDMA-PCM driver
 - Fixes and updates to Cirrus Logic SoC drivers
 - New Qualcomm DSP support
 - New drivers for Analog SSM2305, Atmel I2S controllers, Mediatek
   MT6351, MT6797 and MT7622, Qualcomm DSPs, Realtek RT1305, RT1306 and
   RT5668 and TI TSCS454
 
 HD-audio:
 - Finally better support for some CA0132 boards, allowing Windows
   firmware
 - HP Spectre x360 support along with a bulk of COEF stuff
 - Blacklisting power save default some known boards reported on Fedora
 
 USB-audio:
 - Continued improvements on UAC3 support; now BADD is supported
 - Fixes / improvements for Dell WD15 dock
 - Allow DMA coherent pages for PCM buffers for ARCH, MIPS & co
 
 Others:
 - New Xen sound frontend driver support
 - Cache implementation and other improvements for FireWire DICE
 - Conversions to octal permissions in allover places

00f6f92dbb media: adv7511: fix incorrect clear of CEC receive interrupt
If a CEC message was received and the RX interrupt was set, but
not yet processed, and a new transmit was issues, then the
transmit code would inadvertently clear the RX interrupt and
after that no new messages would ever be received.

Instead it should only clear TX interrupts since register 0x97
is a clear-on-write register.

a024ee14cd media: ov772x: correct setting of banding filter
The banding filter ON/OFF is controlled via bit 5 of COM8 register.  It
is attempted to be enabled in ov772x_set_params() by the following line.

	ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, 1);

But this unexpectedly results disabling the banding filter, because the
mask and set bits are exclusive.

On the other hand, ov772x_s_ctrl() correctly sets the bit by:

	ret = ov772x_mask_set(client, COM8, BNDF_ON_OFF, BNDF_ON_OFF);

The CEC receive buffer was not always cleared correctly. The
datasheet was a bit confusing since sometimes it mentioned that the
bit in CEC register 0x4a had to be toggled, and sometimes it suggested
it was a 'Clear-on-write' bit. But it really needs to be toggled.

The patch also enables/disables the CEC irqs after the other irq are
enabled/disabled instead of doing it before. It may not matter, but it
feels more logical to do it in that order, and the implementation that
we (Cisco) have used until now and that is known to be reliable also
did it in that order.

50eea4ab91 media: i2c: adv748x: Fix pixel rate values
The pixel rate, as reported by the V4L2_CID_PIXEL_RATE control, must
include both horizontal and vertical blanking. Both the AFE and HDMI
receiver program it incorrectly:

- The HDMI receiver goes to the trouble of removing blanking to compute
the rate of active pixels. This is easy to fix by removing the
computation and returning the incoming pixel clock rate directly.

- The AFE performs similar calculation, while it should simply return
the fixed pixel rate for analog sources, mandated by the ADV748x to be
14.3180180 MHz.

struct imx274_frmfmt is instantiated only in the imx274_formats[]
array, where imx274_formats[N].mode always equals N (via enum
imx274_mode).  So .mode carries no information, and unsurprisingly it
is never used.

mbus_code is never used because the 12 bit modes are not implemented.

The colorspace member is also never used, which is normal since the
imx274 sensor can output only one colorspace.

7a2148dfda media: smiapp: fix timeout checking in smiapp_read_nvm
The current code decrements the timeout counter i and the end of
each loop i is incremented, so the check for timeout will always
be false and hence the timeout mechanism is just a dead code path.
Potentially, if the RD_READY bit is not set, we could end up in
an infinite loop.

Fix this so the timeout starts from 1000 and decrements to zero,
if at the end of the loop i is zero we have a timeout condition.

The driver supports the following modes:
- 640x480 30fps
- 640x480 60fps
- 640x480 90fps

Output format is 10bit B&W RAW - MEDIA_BUS_FMT_Y10_1X10.

The driver supports configuration via user controls for:
- exposure and gain;
- horizontal and vertical flip;
- test pattern.

The set_fmt() subdev pad operation for this driver currently does not
only do the driver internal format selection but also do the actual

This doesn't work if the device power control via GPIO lines is enabled.
Because the set_fmt() can be called when the device is placed into power
down mode.

First of all, this fix adds flag to keep track of whether the device starts
streaming or not.  Then, the set_fmt() postpones applying the actual
register setup at this time.  Instead the setup will be applied when the
streaming is started.

Pull media fixes from Mauro Carvalho Chehab:
 "A series of media updates/fixes for 4.17.

  There are two important core fix patches in this series:

   - A regression fix on Kernel 4.16 with causes it to not work with
     some input devices that depend on media core

   - A fix at compat32 bits with causes it to OOPS on overlay, and
     affects the Kernels where the CVE-2017-13166 was backported

  The remaining ones are other random fixes at the documentation and on
  drivers.

  The biggest part of this series is a set of 18 patches for the Intel
  atomisp driver. Currently, it produces hundreds of warnings/errors on
  sparse/smatch, causing me to sometimes ignore new warnings on other
  drivers that are not so broken. This driver is on really poor state,
  even for staging standards: it has several layers of abstraction on
  it, and it supports two different hardware. Selecting between them
  require to add a define (there isn't even a Kconfig option for such
  purpose). Just on this smatch cleanup, I could easily get rid of 8
  "do-nothing" files. So, I'm seriously considering its removal from
  upstream, if I don't see any real work on addressing the problems
  there along this year"
