Subject: [PATCH v2 1/2] platform/chrome: cros_ec_typec: Send enum values to usb_role_switch_set_role()

usb_role_switch_set_role() has the second argument as enum for usb_role.
Currently depending upon the data role i.e. UFP(0) or DFP(1) is sent.
This eventually translates to USB_ROLE_NONE in case of UFP and
USB_ROLE_DEVICE in case of DFP. Correct this by sending correct enum
values as USB_ROLE_DEVICE in case of UFP and USB_ROLE_HOST in case of
DFP.

Fixes: 7e7def15fa4b ("platform/chrome: cros_ec_typec: Add USB mux control")

It is good practice to add these to the individual change too, so that
the reader doesn't have to go back to the cover letter to determine
what has changed in each patch.

So are you suggesting to move it from cover letter to individual patches?
But then isn't the same thing what cover letter is for?

No, I'm suggesting you keep it both places. Each patch should have a
change log documenting what has changed in the various versions.
