I checked out brgl/gpio/for-next. I opened this mailbox from lore in mutt: https://lore.kernel.org/linux-gpio/20191105231533.GA3478@sol/t.mbox.gz And then I saved each message in the v6 series so I could run 'git am' on each. I thought I should be able to run git am on the whole mailbox file but I wasn't sure if the cover letter and replies would cause a problem. I'd appreciate any suggestions as to how I can resolve this: pdp7@x1:~/linux$ git checkout -b brgl-gpio-for-next brgl/gpio/for-next Branch 'brgl-gpio-for-next' set up to track remote branch 'gpio/for-next' from 'brgl'.
