Not sure I understood that correctly. Do you let Greg pull the togreg branch? If you instead let him pull tags, you don't have to wait in such a situation to apply new patches to a for-next branch. (Or just don't use "togreg" for both, sending PRs to Greg and put patches into next.) > Unfortunately I'm doubtful about whether I can squeeze in a second > pull request this cycle, so they may get queued up for next cycle. > A bit of bad timing :( It's not a big problem for me. There is still much to do (also a bit in drivers/iio) before I tackle the final bits of my quest and actually change struct i2c_driver (and so depend on these patches having hit mainline). The only downside for you is, that you might have to endure me asking again for the state of these patches ;-) Thanks for your feedback. Compared to pinging repeatedly and getting no maintainer reply, knowing about your problems is much appreciated.
