* [media] bttv: don't setup the controls if there are no video devicesHans Verkuil2013-11-291-1/+2
| | | | | | | | | | | | | The no_video flag was checked in all other cases except one. Calling v4l2_ctrl_handler_setup() if no_video is 1 will crash. This wasn't noticed before since there are only two card types that set no_video to 1, so this type of hardware is quite rare.

While most of them are just build fixes, there are some fixes for real bugs, as there are a number of drivers using dynamic stack allocation. A few of those might be considered a security risk, if the i2c-dev module is loaded, as someone could be sending very long I2C data that could potentially overflow the Kernel stack. Ok, as using /dev/i2c-* devnodes usually requires root on usual distros, and exploiting it would require a DVB board or USB stick, the risk is not high" * 'topic/kbuild-fixes-for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (28 commits) [media] platform drivers: Fix build on frv arch [media] lirc_zilog: Don't use dynamic static allocation [media] mxl111sf: Don't use dynamic static allocation [media] af9035: Don't use dynamic static allocation [media] af9015: Don't use dynamic static allocation [media] dw2102: Don't use dynamic static allocation [media] dibusb-common: Don't use dynamic static allocation [media] cxusb: Don't use dynamic static allocation [media] v4l2-async: Don't use dynamic static allocation [media] cimax2: Don't use dynamic static allocation [media] tuner-xc2028: Don't use dynamic static allocation [media] tuners: Don't use dynamic static allocation [media] av7110_hw: Don't use dynamic static allocation [media] stv090x: Don't use dynamic static allocation [media] stv0367: Don't use dynamic static allocation [media] stb0899_drv: Don't use dynamic static allocation [media] dvb-frontends: Don't use dynamic static allocation [media] dvb-frontends: Don't use dynamic static allocation [media] s5h1420: Don't use dynamic static allocation [media] uvc/lirc_serial: Fix some warnings on parisc arch ...
| * [media] cimax2: Don't use dynamic static allocationMauro Carvalho Chehab2013-11-081-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dynamic static allocation is evil, as Kernel stack is too low, and compilation complains about it on some archs: drivers/media/pci/cx23885/cimax2.c:149:1: warning: 'netup_write_i2c' uses dynamic stack allocation [enabled by default] Instead, let's enforce a limit for the buffer. Considering that I2C transfers are generally limited, and that devices used on USB has a max data length of 64 bytes for the control URBs. So, it seem safe to use 64 bytes as the hard limit for all those devices. On most cases, the limit is a way lower than that, but this limit is small enough to not affect the Kernel stack, and it is a no brain limit, as using smaller ones would require to either carefully each driver or to take a look on each datasheet.

While it is hard to pinpoint to the reasons, I believe that it is mainly due to: 1) there are several patch series ready, but depending on DT review. I decided to grant some extra time for DT maintainers to look on it, as they're expecting to have more time with the changes agreed during ARM mini-summit and KS.

Unfortunately, the CX88_AUDIO_WM8775 enum is 0 as well, so boards that do not have the wm8775 still try to load and use that driver. Change it to 1 to fix this.

Printing an error message if @work wasn't in the queue is wrong.

* [media] cx23885: Add DTV support for Mygica X8502/X8507 boardsMauro Carvalho Chehab2013-08-223-2/+30
| | | | | | | | | | | | | | Those boards were missing the ISDB-T support. Most of the work on this patch were done by Alfredo. My work here were to port this patch from Kernel 3.2 to upstream, fix the issue caused by the set_frontend bad hook, and add the Kconfig bits. Tested on a X8502 board rebranded as: "Leadership - Placa PCI-e de Captura de Vídeo Híbrida" - product code 3800.

* [media] cx23885-dvb: use a better approach to hook set_frontendMauro Carvalho Chehab2013-08-222-8/+18
| | | | | | | | | | | | | | When the frontend drivers got converted to DVBv5 API, the original hook that tracked when a frontend is set got removed, being replaced by an approach that would use the gate control. That doesn't work fine with some boards. Also, the code were called more times than desired. Replace it by a logic that will hook the dvb set_frontend ops, with works with both DVBv3 and DVBv5 calls.

* [media] cx23885[v4]: Fix interrupt storm when enabling IR receiverLuis Alves2013-08-013-2/+41
| | | | | | | | | | | | | | | | | | | | | | Apparently the Flatiron genereates an interrupt after the built-in self test for each of its left and right channels has completed. Apparently Conexant wire-OR'ed the Flatiron's interrupt output with the interrupt output of the CX23885 A/V core. Those interrupts need to be handled, otherwise, they generate an interrrupt request storm. So: - Add flatiron readreg and writereg functions prototypes on a new header file; - Modify the av interrupt handler to cleanup flatiron IRQs if no other interrupt handling happens.

| | | | | | | | | | | | | | | | | | | | | | The cx88 driver has one v4l2_device, but the video nodes are owned by two different PCI busses. So the dev_parent pointer should be set to the correct parent bus, otherwise sysfs won't show the correct device hierarchy. This broke starting in 3.6 after a driver change, so this patch resurrects the correct behavior.
