dmaengine: coh901318: fix function return types build warnings
A recent patch that removed coh901318_control() replaced it with a number of pointers to existing functions, but those unfortunately have the wrong return type and need to be changed to return an 'int' with an error value rather than a 'void' to avoid these build warnings: drivers/dma/coh901318.c:2697:32: warning: assignment from incompatible pointer type base->dma_slave.device_config = coh901318_dma_set_runtimeconfig; ^ drivers/dma/coh901318.c:2698:31: warning: assignment from incompatible pointer type base->dma_slave.device_pause = coh901318_pause; ^ drivers/dma/coh901318.c:2699:32: warning: assignment from incompatible pointer type base->dma_slave.device_resume = coh901318_resume The coh901318_base_init function has the correct return type already, but needs to be marked 'static' to avoid a sparse warning about a missing declaration.
