Okay, I think I know the issue. Another person commented (Dan Carpenter)
that the function needs to be min_t, I'm guessing so the function
returns the value as the correct type. But one thing I'm wondering is,
why I didn't I get a compiler error when I compiled the kernel myself?
Also-- this is just a general question, when we work on drivers I'm
guessing we don't need to include header files from include/linux,
right?
