[PATCH v2 0/2] soundwire: stream: uniquify dev_err() logs

[PATCH v2 0/2] soundwire: stream: uniquify dev_err() logs

[Bard Liao]

There are a couple of duplicate logs which makes harder than needed to
follow the error flows. Add __func__ or make the log unique.
This series also changed some uses of "dev_err(bus->dev," where the stream
may depend on multiple managers/buses.

v2:
- Split the original patch into two patches

Pierre-Louis Bossart (2):
  soundwire: stream: remove bus->dev from logs on multiple buses
  soundwire: stream: uniquify dev_err() logs

[PATCH v2 1/2] soundwire: stream: remove bus->dev from logs on multiple buses

[Bard Liao]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

A stream may depend on multiple managers/buses, e.g. for the multiple
amplifier case. It's incorrect to use bus->dev in this case.
