Subject: [RFC PATCH v2 19/22] sound: soc: qcom: qusb6: Ensure PCM format is supported by USB audio device
Date: Wed, 25 Jan 2023 19:14:21 -0800	[thread overview]
Message-ID: <20230126031424.14582-20-quic_wcheng@quicinc.com> (raw)
In-Reply-To: <20230126031424.14582-1-quic_wcheng@quicinc.com>

Check for if the PCM format is supported during the hw_params callback.  If
the profile is not supported then the userspace ALSA entity will receive an
error, and can take further action.
