Subject: [PATCH V2 1/1] ASoC: compress: propagate the error code from the compress framework
Date:   Thu, 24 Feb 2022 17:48:33 +0530
Message-ID: <ca6d05bccf692c7e8ab9aa00f08878f163e524b1.1645704570.git.quic_rbankapu@quicinc.com>
In-Reply-To: <cover.1645704570.git.quic_rbankapu@quicinc.com>
References: <cover.1645704570.git.quic_rbankapu@quicinc.com>

Propagate the error code from the compress framework for the timestamp
query. This error code will be used by the client to handle the
error case scenarios gracefully.
