Subject: [Qemu-devel] [PATCH for-4.0] hmp: Fix drive_add ... format=help crash
Date: Fri,  5 Apr 2019 13:45:13 +0200	[thread overview]
Message-ID: <20190405114513.3141-1-armbru@redhat.com> (raw)

drive_new() returns null without setting an error when it provided
help.  add_init_drive() assumes null means failure, and crashes trying
to report a null error.
