Meta-comment, please fix your email client up. The "To:" line was
incorrect, and when applying this patch I get the following:
---
✗ [PATCH v1] usb: typec: altmodes/displayport: Signal hpd when configuring pin assignment
+ Acked-by: Heikki Krogerus <heikki.krogerus@xxxxxxxxxxxxxxx> (✓ DKIM/intel.com)
---
✗ BADSIG: DKIM/google.com
So, is this a fake google.com address?
I'll take this this time, but please fix your system up going forward.
thanks,
greg k-h
