Builds fine here.

In future, you might want to bundle all 3 of your patches either into 1 
patch (while they are changes which can be done separately, it's all 
fixes to one type of problem in relation to one function, so personally 
I'm okay with that) or send it as a series, so that it's clear to 
everyone that they're all related fixes.

Additionally, having the same patch subject line for two patches sent in 
short succession is a bit confusing - in future, try and avoid that.
