Commit Message

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.

It's only redundant in the QCOM case... This would remove all error logs
for other codecs, e.g. see

rt711_sdca_sdw_probe
cs35l56_sdw_probe
wcd9390_probe

Looks like the wsa884x-codec is the chatty driver, others are just fine
with the existing code.
