Subject: net: ax25: %x specifier misuse in kernel?

In ax25_info_show of af_ax25.c:1891, linux-5.1.
The pointer ax25 is cast to long type to print out.

Why it prints the a pointer 'ax25' use %8.8lx rather than %p?
If it really want to print the value of ax25, it should use %px.

Also, I  scan the kernel code and notice that most of the pointers cast to long or unsigned long type to print out are marked with __iomem.
Is it a misuse of %x?

Thanks.
