Hi, I managed to trigger a divide by 0 in the v4l compat code with the mem2mem test module; I suspect perhaps it shouldn't have been returning a 0 pixel wide picture, but either way it seems right to guard this divide by 0 in the compatibility layer. Tested on 2.6.36 (ubuntu build, but the code in this is the same as upstream), but ***not tested with a real video device***. Signed-off-by:

Somehow, I managed to screw things up when reworking the rdev/idev split patch from David, and started trying to get ir_input_dev from idev instead of rdev, thus resulting in button presses hanging the system. This fixes it. Signed-off-by:

These parameters need to be configurable based on the host system. They can now be communicated through the s_config call. The old CONFIG_OLPC_XO_1 selector was not correct; this kind of arrangement wouldn't allow for a universal kernel that would work on both laptops. Certain parts of the probe routine had to be moved later (into s_config), because we can't do any I/O until we know which I/O method has been selected through this mechanism. Signed-off-by:

The Digital Everywhere firmware have the shortcoming that ca_info_enq and ca_info are not supported. This means that we can never retrieve the correct ca_system_id to present in the CI message CA_INFO. Currently the driver uses the application id retrieved using app_info_req and app_info, but this id only match the correct ca_system_id as given in ca_info in some cases. This patch adds a parameter to the driver in order for the user to override what will be returned in the CA_INFO CI message. Up to four ca_system_ids can be specified. This is needed for users with CAMs that have different manufacturer id and ca_system_id and that uses applications that take this into account, like MythTV. Signed-off-by:

With the v4l2_i2c_new_subdev* functions now supporting loading modules based on modaliases, replace the hardcoded module name passed to those functions by NULL. The sub-devices without a listed module name don't result in and I2C sub-device being created, as they either are IR devices or don't have an I2C address listed. It's thus safe to rely on modaliases only. All corresponding I2C modules have been checked, and all of them include a module aliases table with names corresponding to what the cx18 driver uses.

With the v4l2_i2c_new_subdev* functions now supporting loading modules based on modaliases, don't use the module names hardcoded in platform data by passing a NULL module name to those functions. The only platform using the VPIF capture device (DM646x EVM) hardcodes the module names to invalid values (tvp514x-0 and tvp514x-1). As this is already broken, there's no risk of breaking it more.

When creating a new sub-device, The V4L I2C subdev API has historically required drivers to pass the name of the module that implements support for the I2C device. I2C modules can be loaded based on modaliases instead of the module name. As the I2C device type name is already available to the v4l2_i2c_new_subdev* functions, make the module name argument optional and create a modalias based on the type name when no module name is provided. All in-tree drivers call those functions with a non-NULL module name argument, this change is thus harmless. Signed-off-by:
