Nb: both Fedora 14's and Ubuntu 10.10's 2.6.35 kernels have a considerably newer IR stack than upstream 2.6.35, but this patch should still be relevant to both, since I don't see it yet in the Fedora tree, and the Ubuntu patches are more or less identical to at least the first round of IR stack update patches in the Fedora kernel. (Hm, I should actually give the Ubuntu folks some updated patches, but I think they may be pretty well frozen already...) I'll take care of updating the IR bits in the Fedora kernel, and will point some Ubuntu folks in this direction as well. -- Jarod Wilson ja...@wilsonet.com -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
