[PATCH v2 0/1] video: Handle HAS_IOPORT dependencies

[Niklas Schnelle]

Hi,

This is a follow up in my ongoing effort of making inb()/outb() and
similar I/O port accessors compile-time optional. Previously I sent this
as a treewide series titled "treewide: Remove I/O port accessors for
HAS_IOPORT=n" with the latest being its 5th version[0]. With a significant
subset of patches merged I've changed over to per-subsystem series. These
series are stand alone and should be merged via the relevant tree such
that with all subsystems complete we can follow this up with the final
patch that will make the I/O port accessors compile-time optional.

The current state of the full series with changes to the remaining subsystems
and the aforementioned final patch can be found for your convenience on my
git.kernel.org tree in the has_ioport branch[1]. As for compile-time vs runtime
see Linus' reply to my first attempt[2].

Changes since v1:
- Moved vga_mm_r(), vga_mm_w(), vga_mm_w_fast() above #ifdef CONFIG_HAS_IOPORT
  to use them in with or without I/O port variants.
- Duplicated vga_r(), vga_w(), vga_w_fast() functions as non-I/O port variants
  to get rid of in-code #ifdef (Arnd)
- Got rid of if (regbase) logic inversion needed for in-code #ifdef

Thanks,
Niklas
