Subject[PATCH trivial next 8/9] staging: ramster: Use vsprintf extention %pf with builtin_return_address
Date
Emit the function name not the address when possible.

builtin_return_address() gives an address. When building
a kernel with CONFIG_KALLSYMS, emit the actual function
name not the address.
