Subject: ath9k: Clarify we only want 32-bit DMA
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1d450cfc97bc223e9f94a2fab888bb168e284448;p=openwrt%2Fstaging%2Fblogic.git

ath9k: Clarify we only want 32-bit DMA

Use DMA_32BIT_MASK to clarify we only want 32-bit DMA
memory. What was there before is also 32-bit but this makes it
clearer
