From 219153c6ed46b064f9c2b0f70dacf21f719751ee Mon Sep 17 00:00:00 2001 From: Oswald Buddenhagen Date: Fri, 26 May 2023 12:16:54 +0200 Subject: [PATCH] ALSA: emu10k1: hide absent 2nd pointer-offset register set from /proc 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.
