From 54a708ca06830c3fe3df8c0001ab33df784701f9 Mon Sep 17 00:00:00 2001 From: Sanchayan Maity Date: Mon, 8 Aug 2016 16:56:17 +0530 Subject: [PATCH] cmd: dfu: Add error handling for failed registration Without this, if g_dnl_register() fails, DFU code continues on blindly and crashes. This fix makes it simply print an error message instead.
