If anyone has any objections, please let me know. ------------------ From: Tomoya MORINAGA commit 8a52f9f347da721b199b7f9dcc0168bbe7d0baae upstream. Currently, during i2c works alone, wait-event timeout is not occurred. However, as CPU load increases, timeout occurs frequently. So, I modified like this patch. Modifying like this patch, I've never seen the timeout event with high load test.
