I was pondering over implications of "grabbing" events over the
weekend and I am not entirely happy with it either. The problem with
grabbing is that your driver does not have any knowledge of how the
events would be processed if left untouched. Right now you assume that
all bells are handled by pcspkr but we could really have alternative
bell implementations. For example we could have "visual" bell that
could flash framebuffer or a bell that is routed through ALSA, etc,
etc. All these alternative bells would not disrupt operation of your
snd_pcsp module but it still would disable the bell because it does
not know better.
