From 5eafab7614e5bcb0901d670c1d24eac83ae36cea Mon Sep 17 00:00:00 2001 From: David Lamparter Date: Tue, 3 Mar 2015 08:56:48 +0100 Subject: [PATCH] lib: silence type range warning in macro While splitting up the CLI input macro is a bit annoying, this seems to be the least annoying way to get rid of the "< 0" comparison warning for unsigned long.
