Drivers are still on staging - some API improvements for getting EDID data from media inputs/outputs - new DVB frontend driver for drx-j (ATSC) - one driver (it913x/it9137) got removed, in favor of an improvement on another driver (af9035) - added a skeleton V4L2 PCI driver at documentation - added a dual flash driver (lm3646) - added a new IR driver (img-ir) - added an IR scancode decoder for the Sharp protocol - some improvements at the usbtv driver, to allow its core to be reused. - added a new SDR driver (rtl2832u_sdr) - added a new tuner driver (msi001) - several improvements at em28xx driver to fix PM support, device removal and to split the V4L2 specific bits into a separate sub-driver - one driver got converted to videobuf2 (s2255drv) - the e4000 tuner driver now follows an improved binding model - some fixes at V4L2 compat32 code - several fixes and enhancements at videobuf2 code - some cleanups at V4L2 API documentation - usual driver enhancements, new board additions and misc fixups" [ NOTE! This merge effective drops commit 4329b93b283c ("of: Reduce indentation in of_graph_get_next_endpoint"). The of_graph_get_next_endpoint() function was moved and renamed by commit fd9fdb78a9bf ("[media] of: move graph helpers from drivers/media/v4l2-core to drivers/of"). It was originally called v4l2_of_get_next_endpoint() and lived in the file drivers/media/v4l2-core/v4l2-of.c. In that original location, it was then fixed to support empty port nodes by commit b9db140c1e46 ("[media] v4l: of: Support empty port nodes"), and that commit clashes badly with the dropped "Reduce intendation" commit. I had to choose one or the other, and decided that the "Support empty port nodes" commit was more important ] * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (426 commits) [media] em28xx-dvb: fix PCTV 461e tuner I2C binding Revert "[media] em28xx-dvb: fix PCTV 461e tuner I2C binding" [media] em28xx: fix PCTV 290e LNA oops [media] em28xx-dvb: fix PCTV 461e tuner I2C binding [media] m88ds3103: fix bug on .set_tone() [media] saa7134: fix WARN_ON during resume [media] v4l2-dv-timings: add module name, description, license [media] videodev2.h: add parenthesis around macro arguments [media] saa6752hs: depends on CRC32 [media] si4713: fix Kconfig dependencies [media] Sensoray 2255 uses videobuf2 [media] adv7180: free an interrupt on failure paths in init_device() [media] e4000: make VIDEO_V4L2 dependency optional [media] af9033: Don't export functions for the hardware filter [media] af9035: use af9033 PID filters [media] af9033: implement PID filter [media] rtl2832_sdr: do not use dynamic stack allocation [media] e4000: fix 32-bit build error [media] em28xx-audio: make sure audio is unmuted on open() [media] DocBook media: v4l2_format_sdr was renamed to v4l2_sdr_format ...

* [media] cx231xx: fix double free and leaks on failure path in ↵Alexey Khoroshilov2013-10-171-53/+57
| | | | | | | | | | | | | | | | | | cx231xx_usb_probe() There are numerous issues in error handling code of cx231xx initialization. Double free (when cx231xx_init_dev() calls kfree(dev) via cx231xx_release_resources() and then cx231xx_usb_probe() does the same) and memory leaks (e.g. usb_get_dev() before (ifnum != 1) check in cx231xx_usb_probe()) are just a few of them. The patch fixes the issues in cx231xx_usb_probe() and cx231xx_init_dev() by moving usb_get_dev(interface_to_usbdev(interface)) below in code and implementing proper error handling.

Below is an updated patch for the OTG102 device against http://git.linuxtv.org/hverkuil/media_tree.git/shortlog/refs/heads/cx231xx, kernel version 3.8. With further testing it appears the extra clauses in cx231xx-cards.c were not necessary (in static in cx231xx_init_dev and static int cx231xx_usb_probe), so those have been also been removed.

* [media] cx231xx: Improve signal reception for PV SBTVDMauro Carvalho Chehab2013-03-041-2/+2
| | | | | | | | | | | | | | | | Instead of using 3.3 MHz IF, use 4MHz. That's the standard value for the demod, and, while it can be adjusted, 3.3 MHz is out of the recommended range. So, let's stick with the default. With regards to the IF voltage level, instead of using 0.5 V(p-p) for IF, use 2V, giving a 12dB gain. The rationale is that, on PixelView SBTVD Hybrid, even 2V(p-p) would be in the nominal range for IF, as the maximum range on this particular device is 3V. A higher gain here should help to improve reception under weak signals. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
