From 0d813d9960444470c4bebb73c2bde6697543fee9 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 3 Nov 2009 12:53:41 +0100 Subject: [PATCH] i2c-pxa: only define 'blue_murder'-function if DEBUG is #defined MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This talkative function is also called on timeouts. As timeouts can happen on regular writes to EEPROMs (no error case), this creates false positives. Giving lots of details is interesting only for developers anyhow, so just use the function if DEBUG is #defined.
