From 8d8706e2f86d28814c1b40a116ffdeca35e4c949 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Wed, 11 Jan 2006 12:17:49 -0800 Subject: [PATCH] lindent rio drivers Run all rio files through indent -kr -i8 -bri0 -l255, as requested by Alan. rioboot.c and rioinit.c were skipped due to worrisome lindent warnings.
