As per the cover note, v6 is based on brgl/gpio/for-kent, not brgl/gpio/for-next:

 The changes from v5:
  - rebased onto Bart's gpio/for-kent branch.
That is the only diff between v5 and v6.  Ironically you should be
applying v5 to your branch :)

Specifically, in my branch the v6 patch is applied to 

e812692b6e9c (brgl/gpio/for-kent) gpio: rcar: Use proper irq_chip name

which is still the HEAD at time of writing.

Applying the patch to for-next also breaks for me at 0004, so your 
patches are probably ok.

You aren't the only one wondering if there is an easier way to apply patches
from lore, especially when there are additional replies in the thread.
To write my demo showing how anyone, not just those that received the 
patches by mail, can rebase v5 onto for-kent to get v6, I ended up 
downloading the mbox.gz, and unzipping and removing the cruft from it.
Fortunately the mbox is chronological, so it was just removing the cover
note and then everything after patch 7.

Surely there is a better way to do this?
Is there a filter for lore or some tool out there that can filter
the returned mbox for you?
