Subject: [PATCH] staging: vchiq: don't leak kernel address
Since commit ad67b74d2469d9b8 ("printk: hash addresses printed with %p"),
an obfuscated kernel pointer is printed at boot:
vchiq: vchiq_init_state: slot_zero = (____ptrval____)
Remove the the print completely, as it's useless without the address.
