Kees Cook 42bc47b353 treewide: Use array_size() in vmalloc() 
The vmalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:

        vmalloc(a * b)

with:
        vmalloc(array_size(a, b))

as well as handling cases of:

        vmalloc(a * b * c)

with:

        vmalloc(array3_size(a, b, c))

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

        vmalloc(4 * 1024)

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.

The Coccinelle script used for this was:

// Fix redundant parens around sizeof().

Kees Cook 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...".

Merge tag 'media/v4.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - 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

Geert Uytterhoeven 4cff79e933 media: Remove depends on HAS_DMA in case of platform dependency 
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

Note:
  - The various VIDEOBUF*DMA* symbols had to loose their dependencies on
    HAS_DMA, as they are selected by several individual drivers.

Hans Verkuil 68afa17322 media: zoran: move to staging in preparation for removal 
This driver hasn't been tested in a long, long time. The hardware is
ancient and pretty much obsolete. This driver also needs to be converted
to newer media frameworks (vb2!) but due to the lack of time and interest
that is unlikely to happen.

So this driver is a prime candidate for removal. If someone is interested
in working on this driver to prevent its removal, then please contact the
linux-media mailinglist.

The atomisp driver has a long list of todo items and little has been done
to address these lately while more has been added. The driver is also not
functional. In other words, the driver would not be getting out of staging
in the foreseeable future. At the same time it consumes developer
resources in order to maintain the flaky code base. Remove it.

Since commit 50b0f0aee8 ("gpu: ipu-csi: add 10/12-bit grayscale
support to mbus_code_to_bus_cfg") the IPU CSI can be configured to
capture 10-bit and 12-bit grayscale formats, expanded to 16-bit
grayscale, in bayer/generic data mode.
This patch adds support for V4L2_PIX_FMT_Y16 captured from sensors
that provide MEDIA_BUS_FMT_Y10_1X10 or MEDIA_BUS_FMT_Y12_1X12 data.

Dmitry Osipenko 17aed9041d media: staging: tegra-vde: Align bitstream size to 16K 
I've noticed that decoding fails sometime if size of bitstream buffer
isn't aligned to 16K, probably because HW fetches data from memory in
a 16K granularity and if the last chunk of data isn't aligned, HW reads
garbage data beyond the dmabuf and tries to parse it.

It tries to access userspace data directly, without calling
get_user(). That should generate OOPS. Thankfully, the right
logic is already there (although commented out).

Mauro Carvalho Chehab e935dbfc9f media: atomisp: remove an impossible condition 
Changeset dc9f65cf9a ("media: staging: atomisp: avoid a warning if 32
bits build") was meant to solve an impossible condition when building
with 32 bits. It turns that this impossible condition also happens wit
64 bits:
	drivers/staging/media/atomisp/platform/intel-mid/atomisp_gmin_platform.c:698 gmin_get_config_var() warn: impossible condition '(*out_len > (~0)) => (0-u64max > u64max)'

After a further analysis, this condition will always be false as, on
all architectures, size_t doesn't have more bits than unsigned long.

Also, the only two archs that really matter are x86 and x86_64, as this
driver doesn't build on other archs (as it depends on X86-specific UEFI
support).

So, just drop the useless code.

Fixes: dc9f65cf9a ("media: staging: atomisp: avoid a warning if 32 bits build")

Mauro Carvalho Chehab 3585fdc77e media: davinci_vpfe: fix vpfe_ipipe_init() error handling 
As warned:
	drivers/staging/media/davinci_vpfe/dm365_ipipe.c:1834 vpfe_ipipe_init() error: we previously assumed 'res' could be null (see line 1797)

There's something wrong at vpfe_ipipe_init():

1) it caches the resourse_size() from from the first region
   and reuses to the second region;

2) the "res" var is overridden 3 times;

3) at free logic, it assumes that "res->start" is not
   overridden by platform_get_resource(pdev, IORESOURCE_MEM, 6),
   but that's not true, as it can even be NULL there.

This patch fixes the above issues by:

a) store the resources used by release_mem_region() on
   a separate var;

b) stop caching resource_size(), using the function where
   needed.
