Subject[PATCH 3.10 119/123] i2c: at91: dont account as iowait
Date
3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

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

commit 11cfbfb098b22d3e57f1f2be217cad20e2d48463 upstream.

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