media: au0828: fix case where STREAMOFF being called on stopped stream causes BUG()

2012-10-28T17:14:15+00:00

commit a595c1ce4c9d572cf53513570b9f1a263d7867f2 upstream.

We weren't checking whether the resource was in use before calling
res_free(), so applications which called STREAMOFF on a v4l2 device that
wasn't already streaming would cause a BUG() to be hit (MythTV).

media: cx25821: Remove bad strcpy to read-only char*

2012-10-02T17:30:35+00:00

commit c854d8883fec59332f0662917f8c94dcfb1c405d upstream.

The strcpy was being used to set the name of the board.
This was both wrong and redundant,
since the destination char* was read-only and
the name is set statically at compile time.

The type of the name field is changed to const char*
to prevent future errors.

USB: jl2005bcd: remove __devinit* from the struct usb_device_id table

2012-09-14T17:00:21+00:00

commit ec063351684298e295dc9444d143ddfd6ab02df8 upstream.

This structure needs to always stick around, even if CONFIG_HOTPLUG
is disabled, otherwise we can oops when trying to probe a device that
was added after the structure is thrown away.

Thanks to Fengguang Wu and Bjørn Mork for tracking this issue down.

uvcvideo: Reset the bytesused field when recycling an erroneous buffer

2012-09-14T17:00:20+00:00

commit 8a3f0ede2b3f5477122060af1a816c6bbf09fcd2 upstream.

Buffers marked as erroneous are recycled immediately by the driver if
the nodrop module parameter isn't set. The buffer payload size is reset
to 0, but the buffer bytesused field isn't. This results in the buffer
being immediately considered as complete, leading to an infinite loop in
interrupt context.

Fix the problem by resetting the bytesused field when recycling the
buffer.

media: cx231xx: don't DMA to random addresses

2012-07-19T15:58:54+00:00

commit a7deca6fa79d5c65575532e780f3c93f6bf8ddad upstream.

Commit 7a6f6c29d264cdd2fe0eb3d923217eed5f0ad134 (cx231xx: use
URB_NO_TRANSFER_DMA_MAP) was intended to avoid mapping the DMA buffer
for URB twice. This works for the URBs allocated with usb_alloc_urb(),
as those are allocated from cohernent DMA pools, but the flag was also
added for the VBI and audio URBs, which have a manually allocated area.
This leaves the random trash in the structure after allocation as the
DMA address, corrupting memory and preventing VBI and audio from
working. Letting the USB core map the buffers solves the problem.

commit 31c5f0c5e25ed71eeced170f113bb590f2f1f6f3 upstream.

Properly validate the user-supplied index against the number of inputs.
The code used the pin local variable instead of the index by mistake.
