Hi Lee and Thierry,
I know that we're still on New Year vibes, so some things are not up to full
steam for now; but since we're close to v6.7 release and v6.8 merge window,
hence allow me to ask:
Stephen Rothwell is still complaining about backlight tree build failure
due to f7baa9ccef93b, yet it has not been fixed so far. Has the culprit
been dropped/reverted as he requested? The worst case is the culprit slips
through and become part of backlight PR and Linus will likely not happy
with the build regression (maybe he had to fix by himself).
Thanks.
