Subject: usb: dwc3: replace %p with %pK
From: Felipe Balbi <[email protected]>
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.
