[Qemu-ppc] [PATCH 05/10] pseries: Cleanup error handling in spapr_vga_in


From: David Gibson
Subject: [Qemu-ppc] [PATCH 05/10] pseries: Cleanup error handling in spapr_vga_init()
Date: Fri, 15 Jan 2016 23:00:39 +1100

Use error_setg() to return an error rather than an explicit exit().
Previously it was an exit(0) instead of a non-zero exit code, which was
simply a bug.  Also improve the error message.

While we're at it change the type of spapr_vga_init() to bool since that's
how we're using it anyway.
