From b627eb461bb281a00b543e72e74edc197b5f7b5e Mon Sep 17 00:00:00 2001 From: Przemyslaw Marczak Date: Fri, 28 Feb 2014 18:53:37 +0100 Subject: [PATCH] usb: dfu: add static alt num count in dfu_config_entities() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 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.
