Simplify locking by using the V4L2 core lock mechanism. This allows us to remove all locking from the i2c module. This will also simplify the upcoming conversion to the control framework. Signed-off-by:

dvb->adapter.priv should also be set to the i2c bus since that's what em28xx_tuner_callback expects. Signed-off-by:

After using the new VIDIOC_DBG_G_CHIP_NAME ioctl I realized that the matching by name possibility is useless. Just drop it and rename MATCH_SUBDEV_IDX to just MATCH_SUBDEV. The v4l2-dbg utility is much better placed to match by name by just enumerating all bridge and subdev devices until chip_name.name matches. Signed-off-by:

Only enable this ioctl if the VIDEO_ADV_DEBUG config option is set. This prevents abuse from both userspace and kernelspace (some bridge drivers abuse DBG_G_CHIP_IDENT, lets prevent that from happening again with this ioctl). Signed-off-by:

The get_rf_strength op in tuner-simple is valid only for the radio mode. But due to the way get_signal in analog_demod_ops was designed it would overwrite the signal value with a bogus value when in TV mode. Pass a pointer to the signal value instead, and when not in radio mode leave it alone in the tuner-simple. This broke in commit 030755bd (tuner-core: call has_signal for both TV and radio) in kernel 3.6. Before that this was working correctly. That commit did the right thing, but what wasn't realized at the time was that tuner-simple should have been updated as well to restrict setting the signal strength to the radio mode only.

The get_afc op in tda9887 is valid only for the radio mode. But due to the way get_afc in analog_demod_ops was designed it would overwrite the afc value with a bogus value when in TV mode. Pass a pointer to the afc value instead, and when not in radio mode leave it alone in the tda9887. This broke a long time ago in 2.6.19 when the get_afc op was introduced. Before that the afc was only set for radio mode in the tda9887. Signed-off-by:

Make the sensor subdevs host_data hold a pointer to struct fimc_source_info, which is defined in the driver's public header, rather than a pointer to struct fimc_sensor_info which is specific to exynos4-is media device driver. The purpose of this change is to allow easier reuse of the fimc-lite module in the exynos5-is driver, which should similarly store a pointer to struct fimc_source_info instance in the sensor's subdev host_data.

Get the sensor subdev by walking media graph in both cases: when the device is used as a subdev only and through video node. This allows to not dereference the pipeline->subdevs[] array and makes the module more generic and easier to re-use in other media driver. Signed-off-by:

Symbol rate ratio were using a rough calculus, as the code was limited to 32 bits arithmetic. Change it to 64 bits, in order to better estimate the bandwidth low-pass filter on the demod. This should reduce the noise and improve reception. Reported-by:

Using 'i' for the guard interval temporary var is a bad idea, as 'i' is generally used by "anonymous" indexes. Let's rename modulation, fec and guard interval temp vars with a meaningful name, as that makes easier to understand the code and avoids cut-and-paste types of error. Signed-off-by:
