[PATCH v3 1/3] soundwire: bus: suppress probe deferral errors
Posted by Johan Hovold 1 year, 5 months ago
Soundwire driver probe errors are currently being logged both by the bus
code and driver core:

	wsa884x-codec sdw:4:0:0217:0204:00:0: Probe of wsa884x-codec failed: -12
	wsa884x-codec sdw:4:0:0217:0204:00:0: probe with driver wsa884x-codec failed with error -12

Drop the redundant bus error message, which is also incorrectly being
logged on probe deferral:

	wsa884x-codec sdw:4:0:0217:0204:00:0: Probe of wsa884x-codec failed: -517

Note that no soundwire driver uses the driver struct name field, which
will be removed by a follow-on change.
