Could you apply this patch to linux-2.6.30?
If impossible, this patch is not necessary because clock-sh7785.c will modify in linux-2.6.31.

This patch looks like a workaround for the issue solved by this patch:

Thank you for your comment.

Because the patch was due to be applied linux-2.6.31, a problem remains linux-2.6.30. However since linux-2.6.30 had already been released, my patch became unnecessary :)

Thanks,
