i2c-eg20t: change timeout value 50msec to 1000msec
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. Signed-off-by: Tomoya MORINAGA <tomoya.rohm@gmail.com> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>
