When connecting to some DisplayPort partners, the initial status update after entering DisplayPort Alt Mode notifies that the DFP_D/UFP_D is not in the connected state. This leads to sending a configure message that keeps the device in USB mode. The port partner then sets DFP_D/UFP_D to the connected state and HPD to high in the same Attention message. Currently, the HPD signal is dropped in order to handle configuration.
This patch saves changes to the HPD signal when the device chooses to configure during dp_altmode_status_update, and invokes sysfs_notify if necessary for HPD after configuring.

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@linux.intel.com (✓ 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,
