From 26c93df03a8a8c2c0fb130d3e890ce507994566d Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Fri, 29 May 2009 15:10:37 -0700 Subject: [PATCH] Run Nindent on sample/mdiskchk.c Automatically reformat sample/mdiskchk.c using Nindent. Do this for all files except HDT, gPXE and externally maintained libraries (zlib, tinyjpeg, libpng). Signed-off-by: H.
