The Coverity checker spotted the following "we dereference d->fe only when we know it's NULL" bug: <-- snip --> ... static int dibusb_dib3000mb_frontend_attach(struct dvb_usb_device *d) { ... if ((d->fe = dib3000mb_attach(&demod_cfg,&d->i2c_adap,&st->ops)) == NULL) { d->fe->ops.tuner_ops.init = dvb_usb_tuner_init_i2c; d->fe->ops.tuner_ops.set_params = dvb_usb_tuner_set_params_i2c; return -ENODEV; } ... <-- snip --> Signed-off-by:Patrick Boettcher <pb@linuxtv.org> Signed-off-by:

There are several boards on V4L that can work with several different helper modules for audio/video encoding/decoding and similar stuff. This patch adds the capability of choicing between autoselecting the pertinent helper modules for each driver, or to manually selecting them. Acked-by:

Several audio/video encoders/decoders were just bound as if they were part of the core driver. In fact, they are generic enough to be used by other drivers as well, since they use I2C event bus to communicate. Signed-off-by: -

when checking the -Wextra signedness warnings issued by gcc 4.1 I came across this one: drivers/media/video/vivi.c:1001: warning: comparison of unsigned expression < 0 is always false Since videobuf_reqbufs() returns negative values on errors the current code does no real error checking since gcc removes the comparison. This patch fixes this issue by making ret a normal, signed integer. Signed-off-by:

Several changes at register stuff were done since commit b45009b0, but I've forgot to add the copyright line for this. Those changes allowed cx88 to have multiple tuners, allowing it to support hardware with separated radio and video tuners. It also allows binding a tuner to an specific i2c address. Signed-off-by:

cx88-alsa can be compiled in (in distro built kernels, for example), but not used. In those cases, the audio DMA restart is needed for proper sound on NICAM channels. This patch enables the DMA restart even with ALSA, but the functions now check if cx88-alsa is really active. Signed-off-by:

Apparently there are two types of knc1 dvb-s plus cards with different tuners (as for the knc1 dvb-s ones). This patch adds support for those cards with subsystem id 1894:0011. Successfully tested by: Benjamin Weber <benny1990@gmail.com> Signed-off-by:

If the FX2 does not reset properly during reboot, it can present an invalid USB device ID and fail to attach. Prevent this situation from occuring by resetting the USB part of the card when the PCI part probes. Also fix the GPIO configurations so that analog capture will not inadvertantly reset the USB part.

1) It sets LNBDCPol differently based on the card type. Now it should work properly for both the kworld and geniatech cards. 2) It stops returning an error for the SEC_VOLTAGE_OFF voltage command (the cx88-dvb level handles the actual voltage on/off, but it still passes the ioctl down to the cx24123 level, which previously rejected the OFF as invalid so the ioctl would report failure) Acked-by:

Tested on x64 with a bttv board. Most Get ioctls are fixed. The only non-completely working one is VIDIOCGAUDIO. All other IOR ioctls give the same results on x86_64 and i386 architectures.
