Subject: [PATCH 0/5] soundwire: add sdw_master_device support on Qualcomm platforms

This patchset provides the support for sdw_master_device and
sdw_master_driver reviewed earlier and accepted as 'sane' by Greg KH.

This patchset only focuses on Qualcomm platforms and addresses all
previous comments and objections from Vinod Koul: there is no driver
used and no overhead added by this patchset. Many thanks to Srinivas
Kandagatla for testing these patches on Qualcomm devices and
contributing the missing DT parsing fix.

The transition from platform devices to sdw_master_devices on Intel
platforms was already provided and will be re-sent separately when
this infrastructure change is agreed.

Pierre-Louis Bossart (4):
  soundwire: bus_type: add master_device/driver support
  soundwire: bus_type: protect cases where no driver name is provided
  soundwire: qcom: fix error handling in probe
  soundwire: qcom: add sdw_master_device support

Srinivas Kandagatla (1):
  soundwire: master: use device node pointer from master device
