Subject: powerpc: Do not redefine NEED_DMA_MAP_STATE
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=06832fc004815b4b43628d21fc81715e8e7cadff;p=openwrt%2Fstaging%2Fblogic.git

powerpc: Do not redefine NEED_DMA_MAP_STATE

kernel/dma/Kconfig already defines NEED_DMA_MAP_STATE, just select it
from CONFIG_PPC using the same condition as an if guard.
