| |
Add the Type C class for plug alternate mode devices which are being registered by the Type C connector class. This ensures that udev events get generated when the plug alt modes are registered.
Signed-off-by: Prashant Malani <pmalani@chromium.org> Cc: Heikki Krogerus <heikki.krogerus@linux.intel.com> ---
Changes in v2: - Changed code to set the class member instead of bus. - Removed the alteration to typec_bus.rst since it's not longer required. - Updated the commit message and subject to reflect the change in code.
v1: https://lore.kernel.org/linux-usb/20201203030846.51669-1-pmalani@chromium.org/
