This is the second and last phase of ensuring that the arguments of write-only ioctls in V4L2 are const. The first phase was 4-5 months ago and added const to s_crop, s_modulator, s_audio, s_audout, (un)subscribe_event, s_freq_hw_seek, s_jpegcomp and s_fbuf. This second phase adds const to s_frequency, s_tuner, s_std and s_register. Actually, for s_std it doesn't add const but changes it to pass the std by value which is more consistent in that particular case. As a result drivers will be aware when they are implementing write-only ioctls (and I saw a few drivers attempting to return data back to the user), and the v4l2 core will know that drivers won't change the argument of a write-only ioctls which simplifies the core debug code. The changes have been compile-tested with the linux-media daily build but I may have missed some more exotic architectures. Ideally I would like to have this merged fairly early on so we have enough time to shake out any remaining compile problems.
