From dba2b2941ca2ebd5275b3b2c6e72678f98f83a8a Mon Sep 17 00:00:00 2001 From: BALATON Zoltan Date: Sat, 23 Apr 2022 11:36:57 +0200 Subject: hw/audio/ac97: Remove unneeded local variables Several functions have a local variable that is just a copy of one of the function parameters. This is unneeded complication so just get rid of these.
