From a7e0548cea45ec60616936c536efbb2a34605093 Mon Sep 17 00:00:00 2001 From: Uwe Hermann Date: Wed, 9 May 2007 10:17:44 +0000 Subject: Fix coding style of flashrom by running indent on all files indent -npro -kr -i8 -ts8 -sob -l80 -ss -ncs *.[ch] Some minor fixups were required, and maybe a few more cosmetic changes are needed. Corresponding to flashrom svn r108 and coreboot v2 svn r2643.
