[PATCH 1/4] usb: typec: ucsi: Clean up UCSI_CABLE_PROP macros

Posted by Jameson Thies 1 year, 11 months ago

Clean up UCSI_CABLE_PROP macros by fixing a bitmask shifting error for
plug type and updating the modal support macro for consistent naming.

Fixes: 3cf657f07918 ("usb: typec: ucsi: Remove all bit-fields")

Tested by building v6.6 kernel.
