[lvc-project] [PATCH 5.10 1/1] soundwire: cadence: Fix error check in cdns_xfer_msg()

[Daniil Dulov]

From: Richard Fitzgerald <rf at opensource.cirrus.com>

commit 7f6bad4dfde0ec1d479fdcbbb62bccdbf3a93bb4 upstream.

_cdns_xfer_msg() returns an sdw_command_response value, not a
negative error code.
