spi: stm32: return the get_irq error
During probe, return the "get_irq" error value instead of -ENOENT. This allows the driver to be defer probed if needed. Signed-off-by: Fabien Dessenne <fabien.dessenne@st.com> Acked-by: Amelie Delaunay <amelie.delaunay@st.com> Signed-off-by: Mark Brown <broonie@kernel.org>
