Subject: [PATCH] KVM: s390: pci: Fix allocation size of aift kzdev elements
Date: Tue, 25 Oct 2022 22:32:33 -0300 [thread overview]
Message-ID: <20221026013234.960859-1-rafaelmendsr@gmail.com> (raw)
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")
