So this looks good but ... it adds a warning to the build:

/stuff/k/git/kernel/Documentation/driver-api/media/v4l2-controls:823: ./include/media/v4l2-ctrls.h:964: WARNING: Invalid C declaration: Expected identifier in nested name. [error at 6]
const * v4l2_ctrl_get_menu (u32 id)
------^

So it looks like something isn't being parsed quite identically?

Thanks,

jon
