From e6453521edcaa6f130946b5f4fcaf28dbc02f2ed Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Tue, 19 Jul 2011 10:06:11 -0700 Subject: [PATCH] mtd: pcmciamtd: remove custom DEBUG() function We don't need a custom DEBUG() macro here. Just use the built-in kernel code with dynamic debugging features.
