[Qemu-devel] [RFC PATCH v1 2/5] hw: Remove assert_no_error usages |
|
Date: |
Mon, 2 Dec 2013 21:50:29 -0800 |
Replace assert_no_error() usages with the error_abort system.
&error_abort is passed into API calls to signal to the Error sub-system
that any errors are fatal. Removes need for caller assertions.
