The idx values passed to cx18_i2c_register() and ivtv_i2c_register() by cx18_init_subdevs() and ivtv_load_and_init_modules() respectively are always in-range, based on how the hw_all bitmask is populated. Previously, the checks were already ineffective because arrays were being dereferenced using the index before the check. Acked-by:

Fix bug introduced in 7757ddda, where instead of bit-negating the bitmask, the bit position was bit-negated instead. Signed-off-by:

A sample resolution of 2us generates more than 300 interrupts per key and this resolution is not needed unless carrier reports are enabled. Revert to a resolution of 10us unless carrier reports are needed. This generates up to a fifth of the interrupts. Signed-off-by:

Without this patch the adv7343 encoder was being set to default configuration which caused display not to work on this board. This patch passes the necessary platform data required for adv7343 encoder to work on da850 evm. Signed-off-by:

The current code was implemented with some default configurations, this default configuration works on board and doesn't work on other. This patch accepts the configuration through platform data and configures the encoder depending on the data passed. Signed-off-by:

- add device_caps support - fix bus_info - fix numerous tuner-related problems due to incorrect tests and setting v4l2_tuner fields to wrong values. - remove (audio) input support from the radio: it doesn't belong there. This also fixed a nasty issue where opening the radio would set dev->input to 5 for no good reason. This was never set back to a valid TV input after closing the radio device, thus leaving it at 5 which is out of bounds of the vinput card array. Signed-off-by:

Convert the meye driver to the control framework. Some private controls have been replaced with standardized controls (SHARPNESS and JPEGQUAL). The AGC control looks like it can be replaced by the AUTOGAIN control, but it isn't a boolean so I do not know how to interpret it. The FRAMERATE control looks like it can be replaced by S_PARM, but again, without knowing how to interpret it I decided to leave it alone. Signed-off-by:

If you only poll for events, then vb2_poll will return POLLPRI | POLLERR if no streaming is in progress. That's not right, it's perfectly valid to poll just for events.

Newer Exynos4 SoC are equipped with a local camera ISP that controls external raw image sensor directly. Such sensors can be connected through FIMC-LITEn (and MIPI-CSISn) IPs to the ISP, which then feeds image data to the FIMCn IP. Thus there can be two busses associated with an image source (sensor). Rename struct s5p_fimc_isp_info describing external image sensor (video decoder) to struct fimc_source_info to avoid confusion. bus_type is split into fimc_bus_type and sensor_bus_type. The bus type enumeration is extended to include both FIMC Writeback input types. The bus_type enumeration and the data structure name in the board files are modified according to the above changes.

The previous method of registering platform entities into the main driver using driver_find() and then iterating over devices bound to a driver was racy and is being removed here. Nothing was preventing module from unloading during a call to try_module_get(driver->owner). Instead, we look up a device first and then check for its driver while holding device lock. The platform sub-devices are looked up and registered to the top level driver. When any sub-device is not yet initialized and ready the main driver's probe() will be deferred. Signed-off-by:
