From b840f8d8fcb3df9e65bb6782a9072897b6ea117d Mon Sep 17 00:00:00 2001 From: Oswald Buddenhagen Date: Thu, 18 May 2023 16:09:43 +0200 Subject: [PATCH] ALSA: emu10k1: improve voice status display in /proc Eliminate the MIDI type, as there is no such thing - the MPU401 port doesn't have anything to do with voices. For clarity, differentiate between regular and extra voices. Don't atomize the enum into bits in the table display. Simplify/optimize the storage.
