Subject: [PATCH] x86/altp2m: add missing break
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Add a missing break in the HVMOP_altp2m_set_visibility case, or else
code flow will continue into the default case and trigger the assert.

Fixes: 3fd3e9303ec4b1 ('x86/altp2m: hypercall to set altp2m view visibility')
