Since I'm the author of both commits this is my bad, sorry.
Stephen, thank you for fixing this in -next.
Chanwoo, Sebastian send a pull-request for an immutable branch with
these changes:
https://lore.kernel.org/linux-pm/ez5ja55dl7w7ynq2wv4efsvvqtk4xyalf4k6agtsuhpgrtlpg3@d6ghlle4cu2q/
Can you please merge the ib-psy-usb-types-signed tag into
extcon.git/extcon-next and then apply Stephen's fix so that Linus
does not get hit by this build error when he merges the extcon
changes for 6.12 ?
Regards,
Hans
