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.

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).

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.

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.

The dm365_ipipe_hw.c and dm365_ipipe.c file check if several table
pointers, declared at davinci_vpfe_user.h, are filled before using
them.
The problem is that those pointers come from struct declarations

struct vpfe_ipipe_yee {

short table[VPFE_IPIPE_MAX_SIZE_YEE_LUT];
};

This is a little bit hashish, but this driver is at staging,
so it won't become worse.

Remove the address_space ->tree_lock and use the xa_lock newly added to
the radix_tree_root. Rename the address_space ->page_tree to ->i_pages,

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"
