Subject: [PATCH v3 5/7] KVM: x86: Use kcalloc to allocate the mce_banks array.
Date: Fri, 13 May 2022 11:20:36 -0700 [thread overview]
Message-ID: <20220513182038.2564643-6-juew@google.com> (raw)
In-Reply-To: <20220513182038.2564643-1-juew@google.com>
Update the array allocations to use the array allocation API: kcalloc.
This sets up pattern for future array allocations, e.g., mci_ctl2_banks.
