What about when this is called from et131x_adjust_link() and et1310_disable_phy_coma()? Really this changelog is annoying. Based on the changelog I was expecting the kcalloc() to be in the same function but it wasn't. So then I have to redo all your work and check every code path. You could have said what the code paths were in your description so I don't have to grovel through it all myself. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
