Subject: [PATCH v2 1/1] mfd: stmfx: fix dev_err_probe call in stmfx_chip_init
Date: Fri, 13 Nov 2020 13:27:25 +0100	[thread overview]
Message-ID: <20201113122725.12971-1-amelie.delaunay@st.com> (raw)

ret may be 0 so, dev_err_probe should be called only when ret is an error
code.

Fixes: 41c9c06c491a ("mfd: stmfx: Simplify with dev_err_probe()")
Signed-off-by: Amelie Delaunay <amelie.delaunay@st.com>
