So increase the internal representation to 64 bits in preparation. Because of these changes the msi3101 driver has been modified slightly to fix a formatting issue (%d becomes %lld), vivi had to be modified as well to cope with the new 64-bit min/max values and the PIXEL_RATE control in a few sensor drivers required proper min/max/def values.

This allows for more compound data structures to be used with the control framework. The existing V4L2_CTRL_FLAG_NEXT_CTRL flag will only enumerate non-compound controls, so a new V4L2_CTRL_FLAG_NEXT_COMPOUND flag is added to enumerate compound controls. Set both flags to enumerate any control (compound or not). Compound control types will start at V4L2_CTRL_COMPOUND_TYPES. In addition, any control that uses the new 'ptr' field or the existing 'string' field will have flag V4L2_CTRL_FLAG_HAS_PAYLOAD set. While not strictly necessary, adding that flag makes life for applications a lot simpler. If the flag is not set, then the control value is set through the value or value64 fields of struct v4l2_ext_control, otherwise a pointer points to the value.

The changes are fairly obvious: basic support for is_ptr types, the type_is_int function is replaced by a is_int bitfield, and v4l2_query_ext_ctrl is added. Note that this patch does not yet add support for N-dimensional arrays, that comes later. So v4l2_query_ext_ctrl just sets elems to 1 and nr_of_dims and dims[] are all zero.

Not a big deal when dealing with simple values, but it can be a problem when dealing with compound types or arrays. So fix this: cluster_changed() sets the has_changed flag, which is used by new_to_cur() instead of having to do another compare.

It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.

The buffer error flag indicates a transient error and can't be used by applications to detect fatal errors. Returning an error from vb2_qbuf() is thus the only real indication that a fatal error occurred. However, this is difficult to handle for multithreaded applications that requeue buffers from a thread other than the control thread. In particular the poll() call in the control thread will not notify userspace of the error. This patch adds an explicit mechanism to report fatal errors to userspace. Drivers can call the vb2_queue_error() function to signal a fatal error. From this moment on, buffer preparation will return -EIO to userspace, and vb2_poll() will set the POLLERR flag and return immediately. The error flag is cleared when cancelling the queue, either at stream off time (through vb2_streamoff) or when releasing the queue with vb2_queue_release().

charset=UTF-8 Content-Transfer-Encoding: 8bit Right now the protocol information is not preserved, rc-core gets handed a scancode but has no idea which protocol it corresponds to. This patch (which required reading through the source/keymap for all drivers, not fun) makes the protocol information explicit which is important documentation and makes it easier to e.g. support multiple protocols with one decoder (think rc5 and rc-streamzap). The information isn't used yet so there should be no functional changes.

While converting it to dynamic_printk might be a good idea, right now it just makes very hard to debug the drivers, as one needs to both pass debug=1 or debug=2 to rc-core and to use the dynamic printk to enable all the desired lines. That doesn't make sense! So, revert to the old way, as a single line is changed, and the debug parameter will now work as expected.
