Alexander Kochetkov ccfc866356 i2c: omap: fix i207 errata handling ... commit 6d9939f651 (i2c: omap: split out [XR]DR and [XR]RDY) changed the way how errata i207 (I2C: RDR Flag May Be Incorrectly Set) get handled. 6d9939f651 code doesn't correspond to workaround provided by errata. According to errata ISR must filter out spurious RDR before data read not after. ISR must read RXSTAT to get number of bytes available to read. Because RDR could be set while there could no data in the receive FIFO. Restored pre 6d9939f651 way of handling errata. Found by code review. Real impact haven't seen. Tested on Beagleboard XM C.
