USB: core: replace %p with %pK
Format specifier %p can leak kernel addresses while not valuing the kptr_restrict system settings. When kptr_restrict is set to (1), kernel pointers printed using the %pK format specifier will be replaced with Zeros. Debugging Note : &pK prints only Zeros as address. If you need actual address information, write 0 to kptr_restrict. echo 0 > /proc/sys/kernel/kptr_restrict [Found by poking around in a random vendor kernel tree, it would be nice if someone would actually send these types of patches upstream - gkh] Signed-off-by: Vamsi Krishna Samavedam <vskrishn@codeaurora.org> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
