dmaengine: usb-dmac: remove unused ‘uchan’
In usb_dmac_of_xlate(), variable ‘uchan’ is initialized but never used, which leads to warning with W=1 drivers/dma/sh/usb-dmac.c: In function ‘usb_dmac_of_xlate’: drivers/dma/sh/usb-dmac.c:655:24: warning: variable ‘uchan’ set but not used [-Wunused-but-set-variable] struct usb_dmac_chan *uchan; So remove it.
