dmaengine: pch_dma: remove unused ‘cookie’
In pd_tx_submit(), variable ‘cookie’ is initialized but never used, which leads to warning with W=1 drivers/dma/pch_dma.c: In function ‘pd_tx_submit’: drivers/dma/pch_dma.c:420:15: warning: variable ‘cookie’ set but not used [-Wunused-but-set-variable] dma_cookie_t cookie; So remove it.
