KVM: s390: pci: Fix allocation size of aift kzdev elements
The 'kzdev' field of struct 'zpci_aift' is an array of pointers to 'kvm_zdev' structs. Allocate the proper size accordingly. Reported by Coccinelle: WARNING: Use correct pointer type argument for sizeof Fixes: 98b1d33dac5f ("KVM: s390: pci: do initial setup for AEN interpretation") Signed-off-by: Rafael Mendonca <rafaelmendsr@gmail.com> Reviewed-by: Christian Borntraeger <borntraeger@linux.ibm.com> Reviewed-by: Matthew Rosato <mjrosato@linux.ibm.com> Link: https://lore.kernel.org/r/20221026013234.960859-1-rafaelmendsr@gmail.com Message-Id: <20221026013234.960859-1-rafaelmendsr@gmail.com> Signed-off-by: Janosch Frank <frankja@linux.ibm.com>
