From 916f11c760fc1c835d3fe10bebc97a02e2ac6b41 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 8 May 2007 00:36:02 -0700 Subject: smsc-ircc2: tidy up module parameter checking To determine whether the user specified a module parameter, use some #defines instead of checking for bare magic numbers.
