[PATCH 4.9 08/41] usb: dwc3: replace %p with %pK

From: Greg Kroah-Hartman
Date: Mon Jul 10 2017 - 13:20:02 EST


4.9-stable review patch. If anyone has any objections, please let me know.

------------------

From: Felipe Balbi <felipe.balbi@xxxxxxxxxxxxxxx>

commit 04fb365c453e14ff9e8a28f1c46050d920a27a4a upstream.

%p will leak kernel pointers, so let's not expose the information on
dmesg and instead use %pK. %pK will only show the actual addresses if
explicitly enabled under /proc/sys/kernel/kptr_restrict.
