random: fix warning message on ia64 and parisc
PATCH 1/1 random: fix warning message on ia64 and parisc
Fix the warning message on the parisc and IA64 architectures to show the correct function name of the caller by using %pS instead of %pF. The message is printed with the value of _RET_IP_ which calls __builtin_return_address(0) and as such returns the IP address caller instead of pointer to a function descriptor of the caller.
The effect of this patch is visible on the parisc and ia64 architectures only since those are the ones which use function descriptors while on all others %pS and %pF will behave the same.
