3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geert Uytterhoeven <geert@linux-m68k.org>
commit 309124e2648d668a0c23539c5078815660a4a850 upstream.
According to full-history-linux commit d3794f4fa7c3edc3 ("[PATCH] M68k update (part 25)"), port operations are allowed on m68k if CONFIG_ISA is defined.
However, commit 153dcc54df826d2f ("[PATCH] mem driver: fix conditional on isa i/o support") accidentally changed an "||" into an "&&", disabling it completely on m68k. This logic was retained when introducing the DEVPORT symbol in commit 4f911d64e04a44c4 ("Make /dev/port conditional on config symbol").
Drop the bogus dependency on !M68K to fix this.
