Subject: [PATCH] usb: dfu: add static alt num count in dfu_config_entities()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Thanks to this multiple call of function dfu_config_entities()
gives continuous dfu alt numbering until call dfu_free_entities().
This allows to store dfu entities in multiple variables.
