2018-11-12soundwire: intel: constify snd_soc_dai_ops structuresJulia Lawall1-2/+2
The snd_soc_dai_ops structures are only stored in the ops field of a snd_soc_dai_driver structure, so make the snd_soc_dai_ops structures const as well. Done with the help of Coccinelle. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Vinod Koul <vkoul@kernel.org>

2018-05-11soundwire: Remove cdns_master_opsShreyas NC1-2/+9
There can be instances where drivers using Cadence IP might want to set sdw_master_ops differently per instance of it's use, so remove the cdns_master_ops and export the APIs. Signed-off-by: Shreyas NC <shreyas.nc@intel.com> Signed-off-by: Vinod Koul <vkoul@kernel.org>
2018-01-08soundwire: intel: fix missing assignment to retColin Ian King1-1/+1
Currently the return status ret is being checked but it has not been updated since the previous check on ret. It appears that assignment of ret from return status of the call to sdw_cdns_enable_interrupt was accidentally ommited. Fix this.
