[PATCH] fixed warning related to spstdc17

[zack leung]

that didn't work but i'm thinking of defining a char array that is  equal
to the size of the processor lock and the isr lock? i figured  that the
processor lock is 64 bits and isr lock is a one bit?
I'm confused on how to make an api define do you have a file i can look at?
