From 37b37faa8a902161602c4bb536101739701b79d0 Mon Sep 17 00:00:00 2001 From: Tomoya MORINAGA Date: Mon, 26 Mar 2012 14:55:25 +0900 Subject: [PATCH] i2c-eg20t: change timeout value 50msec to 1000msec 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.
