From a92b36ed33800435a2356a78489e129aaf30f673 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Sun, 24 Feb 2008 20:03:42 +0100 Subject: i2c-pxa: Misc fixes While working on the PCA9564-platform driver, I sometimes had a glimpse at the pxa-driver. I found some suspicious places, and this patch contains my suggestions. Note: They are not tested, due to no hardware.
