Some drivers, like au0828 are very sensitive to tuner sleep and may
break if the sleep happens too fast. Also, by keeping the tuner alive
for a while could speedup tuning process during channel scan. So,
change the logic to delay the actual sleep to 5 seconds after its
command.
[media] au0828: reset streaming when a new frequency is set
As reported by Trevor, doing several opening/streaming/closing
operations to the demux causes it to fail.
I was able to simulate this bug too. I also noticed that,
sometimes, changing channels with au0828, the same thing
happens.
Most of the issues seem to be due to some hardware bug, that
causes the device to not fill all the URBs allocated. When
the bug happens, the only known fix is to either replug the
device, or to send an USB reset to it.
There's also a hack a the au0828 driver that starts a thread
that tries to reset the device when a package doesn't start
with a sync.
One of the culpits for this bad hardware behavior seem to be
caused by the lack of stopping and restarting the stream every
time a new channel is set.
This patch warrants that the stream will be properly reset
every time the set_frontend callback is called, partially
solving the problem.
A complete fix, however, would also need to check the PM
conditions for the tuner and demux.
This patch remove variables that are initialized with a constant,
are never updated, and are only used as parameter of return.
Return the constant instead of using a variable.
Verified by compilation only.

[media] adv7604: Replace *_and_or() functions with *_clr_set()
The *_and_or() functions take an 'and' bitmask to be ANDed with the
register value before ORing it with th 'or' bitmask. As the functions
are used to mask and set bits selectively, this requires the caller to
invert the 'and' bitmask and is thus error prone. Replace those
functions with a *_clr_set() variant that takes a mask of bits to be
cleared instead of a mask of bits to be kept.

[media] omap3isp: Cancel all queued buffers when stopping the video stream
When stopping a video stream the driver waits for ongoing DMA opeations
to complete for the currently active buffer, but doesn't release the
non-active queued buffers. This isn't a problem in most cases as the
video device is usually closed after the stream is stopped, which will
release all the buffers. However the problem would generate a warning
when switching to videobuf2. Fix it by cancelling all buffers after DMA
operations have completed.
[media] omap3isp: Use the ARM DMA IOMMU-aware operations
Attach an ARM DMA I/O virtual address space to the ISP device. This
switches to the IOMMU-aware ARM DMA backend, we can thus remove the
explicit calls to the OMAP IOMMU map and unmap functions.
[media] omap3isp: queue: Map PFNMAP buffers to device
Userspace PFNMAP buffers need to be mapped to the device like the
userspace non-PFNMAP buffers in order for the DMA mapping implementation
to create IOMMU mappings when we'll switch to the IOMMU-aware DMA
mapping backend.
[media] omap3isp: queue: Fix the dma_map_sg() return value check
dma_map_sg() can merge sglist entries, and can thus return a number of
mapped entries different than the original value. Don't consider this as
an error.
[media] omap3isp: queue: Merge the prepare and sglist functions
In preparation for the switch to the DMA API merge the two functions
that handle buffer preparation for the USERPTR cases (both page-backed
and non page-backed memory).
[media] omap3isp: queue: Move IOMMU handling code to the queue
As a preparation for the switch from the OMAP IOMMU API to the DMA API
move all IOMMU handling code from the video node implementation to the
buffers queue implementation.
[media] omap3isp: video: Set the buffer bytesused field at completion time
The v4l buffer bytesused field is a value that will be returned to
userspace when the buffer gets dequeued. As such it doesn't need to be
set early at buffer queue time. Move the assignment to buffer completion
in the omap3isp_video_buffer_next() function to prepare for the video
buffers queue refactoring.
Replace the OMAP-specific IOMMU API usage by the DMA API for FPC. The
table is now allocated using dma_alloc_coherent() and the related sg
table is retrieved using dma_get_sgtable() for sync operations.

[media] omap3isp: stat: Store sg table in ispstat_buffer
The driver stores the IOMMU mapped iovm struct pointer in the buffer
structure but only needs the iovm sg table. Store the sg table instead
to prepare the migration to the DMA API.
[media] omap3isp: stat: Merge dma_addr and iommu_addr fields
The fields store buffer addresses as seen from the device. The first one
is used with an external DMA engine while the second one is used with
the ISP DMA engine. As they're never used together, merge them.
The WARN_ON statements in the buffer allocation functions try to catch
conditions where buffers would have already been allocated. As the
buffers are explicitly freed right before being allocated this can't
happen.
[media] omap3isp: stat: Rename IS_COHERENT_BUF to ISP_STAT_USES_DMAENGINE
The macro is meant to test whether the statistics engine uses an
external DMA engine to transfer data or supports DMA directly. As both
cases will be supported by DMA coherent buffers rename the macro to
ISP_STAT_USES_DMAENGINE for improved clarity.

Currently stk1160_read_reg() uses a stack-allocated char to get the

This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive
