Subject: vsock/vmci: Clear the vmci transport packet properly when initializing
it
From: HarshaVardhana S A <[email protected]>
commit 223e2288f4b8c262a864e2c03964ffac91744cd5 upstream.
In vmci_transport_packet_init memset the vmci_transport_packet before
populating the fields to avoid any uninitialised data being left in the
structure.
