Subject: pdc202xx_old: remove init_dma_pdc202xx()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=73369d2a15cfe7dceae89a9e70e3d442e4c21576;p=linux-beck.git

pdc202xx_old: remove init_dma_pdc202xx()

Do PDC202xx specific DMA initialization in init_chipset_pdc202xx()
and remove no longer needed init_dma_pdc202xx().
