From 9903fa914aece320599e74b39ae6cf1bebe1a796 Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Sun, 3 Jan 2016 16:05:56 +1100 Subject: [PATCH] ncr5380: Remove LIST and REMOVE macros Printing command pointers can be useful when debugging queues. Other than that, the LIST and REMOVE macros are just clutter. These macros are redundant now that NDEBUG_QUEUES causes pointers to be printed, so remove them.
