Rename V4L2 async notifier functions, replacing "notifier" with "nf" and
removing "_subdev" at the end of the function names adding subdevs as you
can only add subdevs to a notifier. Also wrap and otherwise clean up long
lines.

Arnd Bergmann 0a7790be18 media: subdev: disallow ioctl for saa6588/davinci
The saa6588_ioctl() function expects to get called from other kernel
functions with a 'saa6588_command' pointer, but I found nothing stops it
from getting called from user space instead, which seems rather dangerous.

The same thing happens in the davinci vpbe driver with its VENC_GET_FLD
command.

As a quick fix, add a separate .command() callback pointer for this
driver and change the two callers over to that.  This change can easily
get backported to stable kernels if necessary, but since there are only
two drivers, we may want to eventually replace this with a set of more
specialized callbacks in the long run.

Laurent Pinchart b01edcbd40 media: v4l2-async: Improve v4l2_async_notifier_add_*_subdev() API
The functions that add an async subdev to an async subdev notifier take
as an argument the size of the container structure they need to
allocate. This is error prone, as passing an invalid size will not be
caught by the compiler. Wrap those functions in macros that take a
container type instead of a size, and cast the returned pointer to the
desired type. The compiler will catch mistakes if the incorrect type is
passed to the macro, as the assignment types won't match.

Mike Rapoport e31cf2f4ca mm: don't include asm/pgtable.h if linux/mm.h is already included
Patch series "mm: consolidate definitions of page table accessors", v2.

The low level page table accessors (pXY_index(), pXY_offset()) are
duplicated across all architectures and sometimes more than once.  For
instance, we have 31 definition of pgd_offset() for 25 supported
architectures.

Most of these definitions are actually identical and typically it boils
down to, e.g.

static inline unsigned long pmd_index(unsigned long address)
{
        return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1);
}

static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
{
        return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
}

These definitions can be shared among 90% of the arches provided
XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined.

For architectures that really need a custom version there is always
possibility to override the generic version with the usual ifdefs magic.

These patches introduce include/linux/pgtable.h that replaces
include/asm-generic/pgtable.h and add the definitions of the page table
accessors to the new header.

This patch (of 12):

The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the
functions involving page table manipulations, e.g.  pte_alloc() and
pmd_alloc().  So, there is no point to explicitly include <asm/pgtable.h>
in the files that include <linux/mm.h>.

The include statements in such cases are remove with a simple loop:

	for f in $(git grep -l "include <linux/mm.h>") ; do
		sed -i -e '/include <asm\/pgtable.h>/ d' $f
	done

As warned by cppcheck:

	[drivers/media/dvb-frontends/cx24123.c:434]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour
	[drivers/media/pci/bt8xx/bttv-input.c:87]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour

			...
	[drivers/media/v4l2-core/v4l2-ioctl.c:1391]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour

There are lots of places where we're doing 1 << 31. That's bad,
as, depending on the architecture, this has an undefined behavior.

The BIT() macro is already prepared to handle this, so, let's
just switch all "1 << number" macros by BIT(number) at the header files
with has 1 << 31.

Sakari Ailus 016413d967 media: v4l2-async: Get fwnode reference when putting it to the notifier's list
The v4l2_async_notifier_add_fwnode_subdev() did not take a reference of
the added fwnode, relying on the caller to handle that instead, in essence
putting the fwnode to be added if there was an error.

As the reference is eventually released during the notifier cleanup, this
is not intuitive nor logical. Improve this by always getting a reference
when the function succeeds, and the caller releasing the reference when it
does not *itself* need it anymore.

Luckily, perhaps, there were just a handful of callers using the function.

Arnd Bergmann 0e633f9716 media: davinci-isif: avoid uninitialized variable use
clang warns about a possible variable use that gcc never
complained about:

drivers/media/platform/davinci/isif.c:982:32: error: variable 'frame_size' is uninitialized when used here
      [-Werror,-Wuninitialized]
                dm365_vpss_set_pg_frame_size(frame_size);
                                             ^~~~~~~~~~
drivers/media/platform/davinci/isif.c:887:2: note: variable 'frame_size' is declared here
        struct vpss_pg_frame_size frame_size;
        ^
1 error generated.

There is no initialization for this variable at all, and there
has never been one in the mainline kernel, so we really should
not put that stack data into an mmio register.

On the other hand, I suspect that gcc checks the condition
more closely and notices that the global
isif_cfg.bayer.config_params.test_pat_gen flag is initialized
to zero and never written to from any code path, so anything
depending on it can be eliminated.

To shut up the clang warning, just remove the dead code manually,
it has probably never been used because any attempt to do so
would have resulted in undefined behavior.

Wenwen Wang a26ac6c1be media: isif: fix a NULL pointer dereference bug
In isif_probe(), there is a while loop to get the ISIF base address and
linearization table0 and table1 address. In the loop body, the function
platform_get_resource() is called to get the resource. If
platform_get_resource() returns NULL, the loop is terminated and the
execution goes to 'fail_nobase_res'. Suppose the loop is terminated at the
first iteration because platform_get_resource() returns NULL and the
execution goes to 'fail_nobase_res'. Given that there is another while loop
at 'fail_nobase_res' and i equals to 0, one iteration of the second while
loop will be executed. However, the second while loop does not check the
return value of platform_get_resource(). This can cause a NULL pointer
dereference bug if the return value is a NULL pointer.

This patch avoids the above issue by adding a check in the second while
loop after the call to platform_get_resource().

Steve Longerbeam d079f94c90 media: platform: Switch to v4l2_async_notifier_add_subdev
Switch all media platform drivers to call v4l2_async_notifier_add_subdev()
to add asd's to a notifier, in place of referencing the notifier->subdevs[]
array. These drivers also must now call v4l2_async_notifier_init() before
adding asd's to their notifiers.

There may still be cases where a platform driver maintains a list of
asd's that is a duplicate of the notifier asd_list, in which case its
possible the platform driver list can be removed, and can reference the
notifier asd_list instead. One example of where a duplicate list has
been removed in this patch is xilinx-vipp.c. If there are such cases
remaining, those drivers should be optimized to remove the duplicate
platform driver asd lists.

None of the changes to the platform drivers in this patch have been
tested. Verify that the async subdevices needed by the platform are
bound at load time, and that the driver unloads and reloads correctly
with no memory leaking of asd objects.
