[PATCH v1 2/7] lib/vsprintf: Deduplicate pointer_string()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

There is an exact code at the end of ptr_to_id().
Replace it by calling pointer_string() directly.

This is followup to the commit
  ad67b74d2469 ("printk: hash addresses printed with %p").
