[ Upstream commit eb503004a7e563d543c9cb869907156de7efe720 ]
Currently the following message is observed when the flexcan driver is probed:
flexcan 2090000.flexcan: device registered (reg_base=(ptrval), irq=23)
The reason for printing 'ptrval' is explained at Documentation/core-api/printk-formats.rst:
"Pointers printed without a specifier extension (i.e unadorned %p) are hashed to prevent leaking information about the kernel memory layout. This has the added benefit of providing a unique identifier. On 64-bit machines the first 32 bits are zeroed. The kernel will print ``(ptrval)`` until it gathers enough entropy."
Instead of passing %pK, which can print the correct address, simply remove the entire message as it is not really that useful.
