Thomas Weißschuh f4aa6caa8b usb: core: Don't use %pK through printk 
This is a revert of
commit 2f964780c0 ("USB: core: replace %p with %pK").

When the formatting was changed from %p to %pK that was a security
improvement, as %p would leak raw pointer values to the kernel log.
Since commit ad67b74d24 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
On the other hand, restricted pointers ("%pK") were never meant to be used
through printk(). They can unintentionally still leak raw pointers or
acquire sleeping looks in atomic contexts.

Switch back to regular %p again.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
