[Xen-devel] Uninitialised issue in hvmemul_do_io()

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Hello,

The latest Coverity run identified an issue in hvmemul_do_io()

ioreq_t p; is declared without initialiser.

By following the false branches, it is possible to get to line 230 of
hvm/emulate.c in the X86EMUL_UNHANDLEABLE case and call
hvm_send_assist_req() with a still uninitialised p.

This is Coverity-ID 1215178

~Andrew
