Applied, thanks My build scripts emit the warnings below, please fix them up with the follow up patch. You can get this with W=1 drivers/dma/qcom/qcom_adm.c:180: warning: Function parameter or member 'chan' not described in 'adm_free_chan' drivers/dma/qcom/qcom_adm.c:190: warning: Function parameter or member 'burst' not described in 'adm_get_blksize' drivers/dma/qcom/qcom_adm.c:466: warning: Function parameter or member 'chan' not described in 'adm_terminate_all' drivers/dma/qcom/qcom_adm.c:466: warning: Excess function parameter 'achan' description in 'adm_terminate_all' drivers/dma/qcom/qcom_adm.c:503: warning: Function parameter or member 'achan' not described in 'adm_start_dma' -- ~Vinod
