Hi Vinod, After merging the slave-dma tree, today's linux-next build (x86_64 allmodconfig) produced this warning: WARNING: modpost: missing MODULE_LICENSE() in drivers/dma/fsl-edma-common.o Introduced by commit 6ad069123f03 ("dmaengine: fsl-edma: extract common fsl-edma code (no changes in behavior intended)") -- Cheers, Stephen Rothwell
