BTW, why were all the similar patches that had nothing to do with Tegra sent to the linux-tegra@ mailing list? You also didn't CC the maintainers of drivers/gpu/drm/tegra/ on this patch. Plus this patch has nothing to do with the rtc-linux@ mailing list.

I'm sorry for that. i just get the maintainers and the mail lists by the script get_maintainer.pl. > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ >

It's unlikely that we'll ever need to add to this function. But I'm not a big fan of PTR_ERR_OR_ZERO to be honest, so I'll let this sink in for a bit before applying. Thierry
