Subject: [PATCH 3.12 200/206] i2c: at91: don't account as iowait

From: Wolfram Sang <wsa@...-dreams.de>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 11cfbfb098b22d3e57f1f2be217cad20e2d48463 upstream.

iowait is for blkio [1]. I2C shouldn't use it.
