I rewrite my patch because the patch before i sent have many white space.
Thanks!

I've been debugging the abnormal operation of i2c on octeon.
If a process is terminated by signal in the middle of i2c operation,
next i2c read operation which is done by another process was failed.
So i changed to ignore signal in the middle of i2c operation.
After that the problem was not reproduced.
