Subject[PATCH] dmaengine: at_hdmac: remove unused function
Date
commit 54f8d501e8428 ('dmaengine: remove DMA unmap from drivers')
refactored some code which resulted in an unused function in the at_hdmac
driver:

drivers/dma/at_hdmac_regs.h:350:23: warning: 'chan2parent' defined but
not used [-Wunused-function]

Fixes: 54f8d501e8428 ('dmaengine: remove DMA unmap from drivers')
