Subject[PATCH 5.10 162/717] mfd: stmfx: Fix dev_err_probe() call in stmfx_chip_init()
Date
From: Amelie Delaunay <amelie.delaunay@st.com>

[ Upstream commit d75846ed08e6f4135ec73778575c34d9c0ace993 ]

'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()")
