2014-05-23[media] saa7134: move saa7134_pgtable to saa7134_dmaqueueHans Verkuil6-35/+37
All dmaqueue's use saa7134_pgtable, so move it into struct saa7134_dmaqueue. The videobuf_queue priv_data field now points to the dmaqueue struct. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2014-05-23[media] vb2: fix num_buffers calculation if req->count > VIDEO_MAX_FRAMESPhilipp Zabel1-1/+1
num_buffers can't be bigger than VIDEO_MAX_FRAME. This is assured by: num_buffers = min_t(unsigned int, req->count, VIDEO_MAX_FRAME); However, this value is overriden by: num_buffers = max_t(unsigned int, req->count, q->min_buffers_needed); It should, instead, use the previously calculated value as an input to max_t: num_buffers = max_t(unsigned int, num_buffers, q->min_buffers_needed); Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Reviewed-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
2014-05-23[media] v4l: vb2: Avoid double WARN_ON when stopping streamingLaurent Pinchart1-3/+4
The __vb2_queue_cancel function marks the queue as not streaming and then WARNs when buffers are still owned by the driver. It proceeds to complete all active buffers by calling vb2_buffer_done with the new buffer state set to VB2_BUF_STATE_ERROR in that case. This triggers another WARN_ON due to as new state not being VB2_BUF_STATE_QUEUED while the queue is not streaming. Check buffer ownership and complete all active buffers before marking the queue as not streaming to avoid the double WARN_on.

vb2_get_vma() copy the content of the vma to a new structure but set some of its pointers to NULL. One of this pointer is used by follow_pte() called by follow_pfn() on io memory. This can lead to a NULL pointer derreference. The version of vma that has not been cleared must be used.

2014-05-23[media] s2255: Do not free fw_data until timer handler has actually stopped ↵Kirill Tkhai1-2/+2
using it Function del_timer() does not guarantee that timer was really deleted. If the timer handler is beeing executed at the moment, the function does nothing. So, we have a race between del_timer() and kfree(), and it's possible to use already freed memory in the handler.

em28xx_compression_disable() is a single line function which is called only one time and this call also isn't needed. Register 0x26 is always configured as part of the scaler configuration, which in turn is always done when the resolution changes. And the initial resolution setting is applied at first device open.
