I would like to get them merged if possible. I talked with GregKH several months ago, and he suggested that I should be able to get them merged, even if I am the only user. They provide a good incentive to get others who maintain similar drivers out-of-tree to get them merged as well. I'll post up the code shortly and let the reviewers tear me to shreds. :) Thanks for the input, Ira _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
