Since everyone has an opinion on this return format my prefered is:

	if (ret)
		return -ETIMEDOUT;
	return 0;

I like a clear "return 0;" instead of a "return ret;" where ret is
always zero.

I also like to keep my error path and my success path as separate as
possible.  Handle the errors right away and move them out of the success
path.
