From b1ecd51bdbb0fc0a7026662b03e7e7df9d129ca0 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Wed, 21 Oct 2015 13:46:50 -0200 Subject: [PATCH] xen-platform: Replace assert() with appropriate error reporting Commit dbb7405d8caad0814ceddd568cb49f163a847561 made it possible to trigger an assert using "-device xen-platform". Replace it with appropriate error reporting.
