From 9c29cf51d16f36c6b20b49091a1263a28aba7794 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Thu, 22 Nov 2012 20:48:42 +0100 Subject: [PATCH] staging: line6: drop unused param_dirty bitmap The param_dirty bitmap tracks which parameters have been modified since saving a preset. The bitmap is never used though so we can drop this deadcode.
