Commit Message

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to add HAS_IOPORT as dependency for
those drivers using them.

Note: The HAS_IOPORT Kconfig option was added in v6.4-rc1 so
      per-subsystem patches may be applied independently

 NAK, this hasn't addressed my input for v2.  Arnd also followed up with 
similar observations with v3.

Ah sorry about that, I had marked the mail as TODO but going over it
missed the proposed fix. Changed this to "depends on HAS_IOPORT ||
ARCH_DECSTATION" for v5.

 It has to be MACH_DECSTATION actually, cf. arch/mips/Kconfig.  Thanks.
