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 (✓ 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
