2009-01-27cx25840: ignore TUNER_SET_CONFIG in the command callback.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> These days TUNER_SET_CONFIG is broadcast to the other i2c devices and that triggers a fw load on the cx25840. Ignore this command since cx25840 isn't a tuner and you really do not want to load the firmware that early. Priority: high Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2009-01-16pvrusb2: Code module name directly in printkMike Isely
From: Mike Isely <isely@pobox.com> The name of the pvrusb2 module is not likely to ever change, and there are plenty of other places where the name is directly coded, so there is little utility in using a macro to infer the module name here. In addition, using that macro complicates other uses of the driver involving older kernels where this macro works differently. Yes I know for many places we don't have to worry about that. But my alternative is that I have to build special logic in the pvrusb2 standalone driver to special-case what is otherwise costmetic and that is just plain nuts for something as trivial as this, especially since this change does not at all have any compile time or run time impact on the driver. I'm just removing a nicety that didn't have a lot of value here to begin with. Priority: normal Signed-off-by: Mike Isely <isely@pobox.com>

A new init() command was introduced to do that explicitly for bridge drivers that are converted to use v4l2_subdev, but old drivers that are not yet converted no longer worked.
