[Qemu-devel] [PATCH 21/55] atapi: cleanup/fix mode sense results

[Kevin Wolf <kwolf@redhat.com>]

From: Paolo Bonzini <pbonzini@redhat.com>

The first two bytes (after the 8-byte ATAPI header) are the mode page
number and the number of bytes after the length field itself.  Make
this clear in the code.

The AUDIO_CTL page was filled with wrong values.  It is not anymore in
MMC, but at least keep the values sane.
