Recently I changed the return value of rtas_call() from an unsigned long to
an int.  That patch missed a few places where we declare a variable to
store the result from rtas_call().  This new patch changes those places to
use an int variable instead of a long or unsigned long variable.  Linas
Vepstas pointed this out.
