Subject: m68k/io: Remove useless definition of mmiowb()
X-Git-Tag: v5.4-rc1~1108^2~14
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0f43ca692dcb55108ea9a59c11a1a0e359dba367;p=platform%2Fkernel%2Flinux-rpi.git

m68k/io: Remove useless definition of mmiowb()

m68k includes asm-generic/io.h, which provides a dummy definition of
mmiowb() if one isn't already provided by the architecture.

Remove the useless definition.
