dmaengine: img-mdc: remove unused ‘prev_phys’
In mdc_prep_dma_memcpy(), mdc_prep_dma_cyclic() and mdc_prep_slave_sg()
variable ‘prev_phys’ is initialized but never used, which
leads to warning with W=1
drivers/dma/img-mdc-dma.c: In function ‘mdc_prep_dma_memcpy’:
drivers/dma/img-mdc-dma.c:295:24: warning: variable ‘prev_phys’ set but not used [-Wunused-but-set-variable]
dma_addr_t curr_phys, prev_phys;
drivers/dma/img-mdc-dma.c: In function ‘mdc_prep_dma_cyclic’:
drivers/dma/img-mdc-dma.c:378:24: warning: variable ‘prev_phys’ set but not used [-Wunused-but-set-variable]
dma_addr_t curr_phys, prev_phys;
drivers/dma/img-mdc-dma.c: In function ‘mdc_prep_slave_sg’:
drivers/dma/img-mdc-dma.c:461:24: warning: variable ‘prev_phys’ set but not
used [-Wunused-but-set-variable]
dma_addr_t curr_phys, prev_phys;
So remove it.
