qseecom: Change format specifier %p to %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 0's.
So that %pK will not leak kernel pointers to unprivileged users.
So change the format specifier from %p to %pK.
Debugging Note : &pK prints only Zeros as address. if you need actual
address information, pls echo 0 to kptr_restrict.
$ echo 0 > /proc/sys/kernel/kptr_restrict
