I think the subject doesn't need "for module use" because that's implicit in exporting a symbol.

Also please wrap the commit message at around 72 characters. If you make the lines too short it becomes almost as difficult to readable as if they're too long. Other than these small nitpicks this looks like a reasonable change to me. > > Signed-off-by: Vince Hsu <vinceh@nvidia.com> > --- > > v2: add more description why we need this patch > > drivers/soc/tegra/fuse/fuse-tegra.c | 1 + > 1 file changed, 1 insertion(+) Ben, patch 3/3 has a dependency on this one. Would you prefer to merge this as part of the Nouveau tree or do you want me to provide a stable branch that you can pull in to resolve the dependency? In case of the former: Acked-by: Thierry Reding <treding@nvidia.com>

I'll take the patch, seems the simplest option :) Thanks, Ben. > > In case of the former: > > Acked-by: Thierry Reding <treding@nvidia.com> > > _______________________________________________ > Nouveau mailing list > Nouveau@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/nouveau > -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Some Tegra drivers might be complied as kernel modules, and they need the fuse information for initialization. One example is the GK20A Nouveau driver. It needs the GPU speedo value to calculate frequency-voltage table. So export the tegra_sku_info.
