Hi Florian,quoted
+ /* Clock is optional on most platforms */ + priv->clk = devm_clk_get(dev, NULL); +At least EPROBE_DEFER should be handled here: if (IS_ERR(priv->clk) && PTR_ERR(priv->clk) == -EPROBE_DEFER) return -EPROBE_DEFER;
if (priv->clk == ERR_PTR(-EPROBE_DEFER)) return -EPROBE_DEFER; is a simpler test for one particular error-pointer value. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line in suburbia: sync at 8.8Mbps down 630kbps up According to speedtest.net: 8.21Mbps down 510kbps up
