commit 66b9298878742f08cb6e79b7c7d5632d782fd1e1 (i2c: omap: switch over to do {} while loop) changed the interrupt handler to abort transfers in case interrupt serviced 100 times but commit's comment states that "No functional changes otherwise.". Also, original commit could report status 0 (no error) on aborted transfers. The patch restore original logic. In case interrupt serviced 100 times just quit interrupt handler and don't abort active transfer.
