[Qemu-devel] [PATCH] cuda.c: return error for unknown commands


From: Alyssa Milburn
Subject: [Qemu-devel] [PATCH] cuda.c: return error for unknown commands
Date: Fri, 22 Jan 2016 23:07:24 +0000
User-agent: Mutt/1.5.21 (2010-09-15)

This avoids MacsBug hanging at startup in the absence of ADB mouse
input, by replying with an error (which is also what MOL does) when
it sends an unknown command (0x1c).
