From 37a801c776109dce801875b12525a9eaa12481e6 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Sun, 26 Mar 2006 10:07:35 +1000 Subject: [PATCH] [PATCH] powerpc: legacy_serial loop cleanup We only ever execute the loop once, so let's move it to a function making it more readable. Cleanup patch, no functional change.
