Wolfram Sang ea37818a54 i2c: rcar: revoke START request early ... commit 52df445f29b79006d8b2dcd129152987c0d3bd64 upstream. If we don't clear START generation as soon as possible, it may cause another message to be generated, e.g. when receiving NACK in address phase. To keep the race window as small as possible, we clear it right at the beginning of the interrupt. We don't need any checks since we always want to stop START and STOP generation on the next occasion after we started it. This patch improves the situation but sadly does not completely fix it. It is still to be researched if we can do better given this HW design.
