Subject: [PATCH 0/3] Some fixes for select_usb_power_delivery

Hi, here are some fixes about the attribute "select_usb_power_delivery"
in typec/class.c

===

usb: typec: Set port->pd before adding device for typec_port

This one is about the visibility of the attribute. port->pd should be
set before device_add otherwise the visibility will be false because
port->pd is NULL.

===

usb: typec: Iterate pds array when showing the pd list

This patch fixes a problem about the incorrect fetching of the pointers
to each usb_power_delivery handle.

===

usb: typec: Use sysfs_emit_at when concatenating the string

This patch changes the use of the API from sysfs_emit to sysfs_emit_at
because the buffer address is not aligned to PAGE_SIZE.

===
