[media] soc-camera: remove redundant parameter from .set_bus_param()
The "pixfmt" parameter of the struct soc_camera_host_ops::set_bus_param()
method is redundant, because at the time, when this method is called,
pixfmt is guaranteed to be equal to icd->current_fmt->host_fmt->fourcc.
Remove this parameter and update all drivers accordingly.

[media] drivers/media/video/atmel-isi.c: eliminate a null pointer dereference
The variable isi might be null or might be freed at the point of the call
to clk_put. pclk contains the value that isi->pclk is expected to point to.
The semantic match that finds this problem is as follows:
// <smpl>
@r@
expression E, E1;
identifier f;
statement S1,S2,S3;
@@
if (E == NULL)
{
... when != if (E == NULL || ...) S1 else S2
when != E = E1
*E->f
... when any
return ...;
}
else S3
// </smpl>

Marek Szyprowski <m.szyprowski@samsung.com> |
[media] media: vb2: change queue initialization order
This patch changes the order of operations during stream on call. Now the
buffers are first queued to the driver and then the start_streaming method
is called.
This resolves the most common case when the driver needs to know buffer
addresses to enable dma engine and start streaming. Additional parameter
to start_streaming method have been added to simplify drivers code. The
driver are now obliged to check if the number of queued buffers is high
enough to enable hardware streaming. If not - it can return an error. In
such case all the buffers that have been pre-queued are invalidated.
This patch also updates all videobuf2 clients to work properly with the
changed order of operations.

[media] media: vb2: dma contig allocator: use dma_addr instread of paddr
Use the correct 'dma_addr' name for the buffer address. 'paddr' suggested
that this is the physical address in system memory. For most ARM platforms
these two are the same, but this is not a generic rule. 'dma_addr' will
also point better to dma-mapping api.
