Subject: [PATCH 0/3] usb: typec: ucsi: Ack connector change early

As briefly discussed here
  https://lore.kernel.org/lkml/Zf1XUrG1UbVJWzoz@kuha.fi.intel.com/
acknowledge connector change events along with the first command
in ucsi_handle_connector_change(). The connector lock should be
sufficient to protect the rest of the function and the partner
tasks.

This allows us to remove the Dell quirk in ucsi_acpi.c.
Additionally, this reduces the number of commands that are sent
with an un-acknowleged connector change event.

Christian A. Ehrhardt (3):
  usb: typec: ucsi: Stop abuse of bit definitions from ucsi.h
  usb: typec: ucsi: Never send a lone connector change ack
  usb: typec: ucsi_acpi: Remove Dell quirk
