[PATCH 1/6] ALSA: emu10k1: hide absent 2nd pointer-offset register set from /proc

[Oswald Buddenhagen <oswald.buddenhagen@gmx.de>]

The 2nd register set belongs to the P16V chip (or embedded P17V module),
so there is nothing to show when no such part is present. Gen2 E-MU
cards have a P17V, but it's entirely unused, so we hide it there as
well.
