media: rc: set timeout to smallest value required by enabled protocols · a86d6df8

Sean Young authored Mar 23, 2018

The longer the IR timeout, the longer the rc device waits until delivering
the trailing space. So, by reducing this timeout, we reduce the delay for
the last scancode to be delivered.

Note that the lirc daemon disables all protocols, in which case we revert
back to the default value.

media: rcar-vin: Fix image alignment for setting pre clipping · 536f0f55

Koji Matsuoka authored Apr 12, 2018

In Video Pixel/Line Pre-Clip Register, the setting value can be
set in 1 line unit, but it can only be specified as a multiple of
4 by v4l_bound_align_image function().
So correct that it can be specified in 1 line unit with this patch.

media: omap3isp: fix unbalanced dma_iommu_mapping · b7e1e685

Suman Anna authored Mar 14, 2018

The OMAP3 ISP driver manages its MMU mappings through the IOMMU-aware
ARM DMA backend. The current code creates a dma_iommu_mapping and
attaches this to the ISP device, but never detaches the mapping in
either the probe failure paths or the driver remove path resulting
in an unbalanced mapping refcount and a memory leak. Fix this properly.

media: v4l2-compat-ioctl32: better name userspace pointers · 6dd0394f

Mauro Carvalho Chehab authored Apr 16, 2018

In the past, "up" were an acronym for "user pointer" and "kp" for
"kernel pointer". However, since commit a1dfb4c4 ("media:
v4l2-compat-ioctl32.c: refactor compat ioctl32 logic"), both
are now __user pointers.

So, the usage of "kp" is really misleading there. So, rename
both to just "p32" and "p64" everywhere it occurs, in order to
make peace with this file's namespace.

There are two exceptions to "up/kp" nomenclature: at
alloc_userspace() and at do_video_ioctl().

There, a new userspace pointer were allocated, in order to store
the 64 bits version of the ioctl. Those were called as "up_native",
with is, IMHO, an even worse name, as "native" could mislead of
being the arguments that were filled from userspace. I almost
renamed it to just "p64", but, after thinking more about that,
it sounded better to call it as "new_p64", as this makes clearer
that this is the data structure that was allocated inside this
file in order to be used to pass/retrieve data when calling the
64-bit ready file->f_op->unlocked_ioctl() function.

media: ddbridge: don't uselessly check for dma in start/stop functions · 8b8fcf32

Daniel Scheller authored Apr 16, 2018

The check for a valid ptr in ddb_io->dma isn't really necessary since only
devices that do data transport using DMA are supported by the driver, and
all previous initialisation code (through input_init(), output_init() and
dma_init(), has_dma is always true as it's set in ddb_probe() during
driver load) guarantees the ptr is set.

As a side effect, this silences these sparse warnings (albeit them being
false positives as ddb_io->dma won't change in these functions so the
condition always equals to the same result):

media: atomisp: remove an impossible condition · e935dbfc

Mauro Carvalho Chehab authored Apr 11, 2018

Changeset dc9f65cf ("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.

complex and violates Linux coding style, as it does multiple

	               line 314
	  Unlocked on: line 303

The lock implementation for get event is wrong, as, if an
interrupt occurs, down_interruptible() will fail, and the
routine will call up() twice when userspace calls the ioctl
again.

The bad code is there since when Linux migrated to git, in
2005.

media: isppreview: fix __user annotations · 99ed3dd8

Mauro Carvalho Chehab authored Apr 06, 2018

The 'from' variable at preview_config() expects an __user * type.

However, the logic there does:

from = *(void * __user *) ((void *)cfg + attr->config_offset);

With actually means a void pointer, pointing to a void __ user
pointer. When the first pointer is de-referenced with *(foo),
the type it returns is "void *" instead of "void __user *".

Change it to:
from = *(void __user **) ((void *)cfg + attr->config_offset);

in order to obtain, when de-referenced, a void __user pointer,
as desired.

That prevent those warnings:

if v4l2_subdev_call(..., VENC_GET_FLD,...) fails, it
currently returns a random value. Instead, return 1.

That's probably better than returning 0, as this is very
likely what happens in practice with the current code, as
as the probably of an unititialized 32 bits integer to
have an specific value (0, in this case), is 1/(2^32).

An alternative would be to return an error code, and
let the caller to hint, based on the past received
frame, but that sounds weird.
