The current control used to be per-trigger (i.e., per-cset). However, some parameters are per-channel (like the gain), so each channel now has its own current control structure. Also, zio-dump now shows device and trigger attributes, both standard and extended ones. Signed-off-by:

We will have buffers that use the default operations (the majority) and buffers without file operations for in-kernel activities, like the input subsystem. In the latter case we want the cdev to refuse being openend, so NULL is reserved for that case. Also, add v_op to the buffer, so it can support mmap. Signed-off-by:

Some of them don't apply any more (we made our choices, or the problem has been addressed and fixed elsewhere). Some do but I reworded them. Some still apply unchanged, and are not touched by this patch. Signed-off-by:

zio invokes try_module_get() on buffer, trigger and device owners when they are in use. For devices we still have a little unsafe time. Signed-off-by:
