'PRIx64' won't work with 'sizeof' because its return type changes with the arch,
need to use %zx with 'sizeof'

I am aware that driver doesn't support 32-bits, but build is only broken because
of the format errors in the log formatting, I am for fixing them. Also using
correct format type is good practice.

There are following related errors [1], I am fixing them while merging [2]
please let me know if you request any change in the updated code.
