Subject: [PATCH] soundwire: qcom: Log clk_get("iface") failures
Date:   Fri, 21 Jul 2023 09:49:01 -0700

Failing to acquire the iface clock makes probing of the Qualcomm
SoundWire driver fail without providing any indication to the user. Make
the driver log the error to aid debugging system configuration issues.
