Subject: skge: fix build on 32 bit
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f7b7a365331deb4553944a0b695dd6371614053a;p=openwrt%2Fstaging%2Fblogic.git

skge: fix build on 32 bit

The following is needed as well to fix warning/error about shifting a 32 bit
value 32 bits which occurs if building on 32 bit platform caused by conversion
to using dma_addr_t
