From eeeec230f9405be68ed56a6134dea4b45b0906be Mon Sep 17 00:00:00 2001 From: Rafael Mendonca Date: Tue, 25 Oct 2022 22:32:33 -0300 Subject: [PATCH] KVM: s390: pci: Fix allocation size of aift kzdev elements [ Upstream commit b6662e37772715447aeff2538444ff291e02ea31 ] The 'kzdev' field of struct 'zpci_aift' is an array of pointers to 'kvm_zdev' structs. Allocate the proper size accordingly.
