[PATCH 1/5] m68k/io: Add missing ioremap define guards, fix typo
From: Geert Uytterhoeven <geert@linux-m68k.org>
Date: 2018-07-09 09:31:21
Also in:
lkml, netdev
Subsystem:
m68k architecture, the rest · Maintainers:
Geert Uytterhoeven, Linus Torvalds
- Add missing define guard for ioremap_wt(),
- Move ARCH_HAS_IOREMAP_WT from <asm/io_mm.h> to <asm/kmap.h>, as it
is applicable to Coldfire with MMU, too,
- Fix typo s/ioremap_fillcache/ioremap_fullcache/,
- Add define guard for iounmap() for consistency with other
architectures.
Fixes: 9746882f547d2f00 ("m68k: group io mapping definitions and functions")
Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

v2:
- Move ARCH_HAS_IOREMAP_WT to fix "ioremap_wt redefined" warnings with
m5475evb defconfig.
