From: Felipe Balbi Date: Wed, 17 May 2017 12:57:45 +0000 (+0300) Subject: usb: dwc3: replace %p with %pK X-Git-Tag: v4.13-rc1~185^2~23^2~44 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=04fb365c453e14ff9e8a28f1c46050d920a27a4a;p=karo-tx-linux.git usb: dwc3: replace %p with %pK %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.
