Subject: dma: mv_xor: in mv_xor_device, rename 'common' to 'dmadev'
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8c75979d7ac8cdec927605336aeebea0c7f88f74;p=linux-beck.git

dma: mv_xor: in mv_xor_device, rename 'common' to 'dmadev'

The mv_xor_device structure embeds a 'struct dma_device', which is
named 'common', a not very meaningful name. Rename it to 'dmadev',
which will help avoid confusions later as we merge the mv_xor_device
and mv_xor_chan structures together.
