vsprintf: Fix %ps on non symbols when using kallsyms ...
Using %ps in a printk format will sometimes fail silently and
print the empty string if the address passed in does not match a
symbol that kallsyms knows about. But using %pS will fall back to
printing the full address if kallsyms can't find the symbol. Make
%ps act the same as %pS by falling back to printing the address.
While we're here also make %ps print the module that a symbol
comes from so that it matches what %pS already does. Take this
simple function for example (in a module):
static void test_printk(void)
{
int test;
pr_info("with pS: %pS\n", &test);
pr_info("with ps: %ps\n", &test);
}
Before this patch:
with pS: 0xdff7df44
with ps:
After this patch:
with pS: 0xdff7df44
with ps: 0xdff7df44
