Subject: [PATCH] arm/ftrace: Fix function_return_addr() to
 function_return_address()

The clean up of CALLER_ADDR*() functions required the archs to either
use the default __builtin_return_address(X) (where X > 0) or override
it with something the arch can use. To override it, the arch would
define function_return_address(x).

The arm architecture requires this to be redefined but instead of
defining function_return_address(x) it defined function_return_addr(x).
