* media: media/pci: use vb2_video_unregister_device()Hans Verkuil2020-08-281-1/+1
| | | | | | | | | | | Use vb2_video_unregister_device() to automatically stop streaming at unregister time. This avoids the use of vb2_queue_release() which should not be called by drivers that set vdev->queue.

* media: replace strncpy() by strscpy()Mauro Carvalho Chehab2019-03-291-1/+1
| | | | | | | | | | | The strncpy() function is being deprecated upstream. Replace it by the safer strscpy(). While here, replace a few occurences of strlcpy() that were recently added to also use strscpy().

* media: use strscpy() instead of strlcpy()Mauro Carvalho Chehab2018-09-111-1/+1
| | | | | | | | | | | The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL terminated strings.

* [media] saa7134: fix page size on some archsMauro Carvalho Chehab2015-06-241-3/+3
| | | | | | | | | | | | | | | | | | | | | On some archs, like tile, the PAGE_SIZE is not 4K. In the case of tile arch, it can be either 16KB or 64KB. Due to that, a warning is produced: drivers/media/pci/saa7134/saa7134.h:678:43: warning: large integer implicitly truncated to unsigned type [-Woverflow] This is actually an error, as it will write trach to the DMA size registers. The logic at saa7134-ts already does the right thing: saa_writeb(SAA7134_TS_DMA0, ((dev->ts.nr_packets-1)&0xff)); saa_writeb(SAA7134_TS_DMA1, (((dev->ts.nr_packets-1)>>8)&0xff)); /* TSNOPIT=0, TSCOLAP=0 */ saa_writeb(SAA7134_TS_DMA2, ((((dev->ts.nr_packets-1)>>16)&0x3f) | 0x00)); So, fix the driver to take larger page sizes into account.

* [media] saa7134: add saa7134-go7007Hans Verkuil2014-09-231-0/+532
This patch adds support to saa7134 for 'WIS Voyager or compatible' PCI boards such as the Sensoray model 614 with which this patch was tested. It is a saa7134-based PCI board with a go7007 MPEG encoder. This was a patch when the go7007 was still in staging and was not applied when go7007 was moved to drivers/media since it needed more work. That work is now done and this last piece of go7007 support can now go in.
