Subject: jme: Remove 64 and 40 bit dma_mask
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e4e6c38cab208b369bfc8e9a57186581bf0b9987;p=openwrt%2Fstaging%2Fblogic.git

jme: Remove 64 and 40 bit dma_mask

Although the hardware supports the 64bit DMA address in design,
but later found that it actually not working.
This patch reduced the rang to 32bit.
