Subject: ethernet: qualcomm: use spi instead of spi_device
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=cf9d0dcc5a46f0a3dcb7905aa6ffa8e4bbc1cc99;p=openwrt%2Fstaging%2Fblogic.git

ethernet: qualcomm: use spi instead of spi_device

All spi based drivers have an instance of struct spi_device
as spi. This patch renames spi_device to spi to synchronize
with all the drivers.
