Subject: [PATCH 3/3] crypto: stm32/hash - don't print error on probe deferral
Date: Mon, 27 Apr 2020 08:42:26 +0200	[thread overview]
Message-ID: <20200427064226.6991-4-lionel.debieve@st.com> (raw)
In-Reply-To: <20200427064226.6991-1-lionel.debieve@st.com>

Change driver to not print an error message when the device
probe is deferred for a clock resource.
