* i2c: rcar_i2c: Fix order of restart and clear statusNobuhiro Iwamatsu2014-11-10-2/+2
| | | | | | | | | | In case of repeated START condition, the restart has to be kicked before clear status (MSR register). If it is kicked after clear status, R-Car I2C may transfer data (TXD register) or receive data (RXD register) instead of transferring slave address (MAR register).
