From c852ac80440db9b0a47f48578e9c6303078abbc1 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Mon, 18 Sep 2006 23:26:25 +0100 Subject: [ARM] 3832/1: iop3xx: coding style cleanup Since the iop32x code isn't iop321-specific, and the iop33x code isn't iop331-specfic, do a s/iop321/iop32x/ and s/iop331/iop33x/, and tidy up the code to conform to the coding style guidelines somewhat better.
