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.
