From 2ad6d55e38c51acc4191ea5578caebe3287f6521 Mon Sep 17 00:00:00 2001 From: David Hendricks Date: Mon, 9 Aug 2010 23:13:13 +0000 Subject: [PATCH] Some chips do not require enter/exit sequences. This causes them to be detected and printed multiple times in probe_idregs_* functions where a simple series of enter --> probe/print --> exit calls are made. This patch adds a simple check after each set of those calls to make the functions quit after a chip is found.
