Relocate the machine handling functions from sof-audio.c to core.c to maintain code separation. While doing the move, drop the redundant IS_ERR_OR_NULL(plat_data->pdev_mach) check from sof_machine_unregister() Signed-off-by: Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx> Reviewed-by: Kai Vehmanen <kai.vehmanen@xxxxxxxxxxxxxxx> --- sound/soc/sof/core.c | 95 +++++++++++++++++++++++++++++++++++++ sound/soc/sof/sof-audio.c | 98 --------------------------------------- sound/soc/sof/sof-priv.h | 2 - 3 files changed, 95 insertions(+), 100 deletions(-) diff --git a/sound/soc/sof/core.c b/sound/soc/sof/core.c index d7b090224f1b..a87522ea4301 100644 --- a/sound/soc/sof/core.c +++ b/sound/soc/sof/core.c @@ -13,6 +13,7 @@ #include <sound/soc.h> #include <sound/sof.h> #include "sof-priv.h" +#include "sof-of-dev.h" #include "ops.h" #define CREATE_TRACE_POINTS @@ -143,6 +144,66 @@ void sof_set_fw_state(struct snd_sof_dev *sdev, enum sof_fw_state new_state) } EXPORT_SYMBOL(sof_set_fw_state);
