Subject: [PATCH v1 08/12] ACPI: memhotplug: memory resources cannot be enabled yet
Date: Mon, 7 Jun 2021 21:54:26 +0200 [thread overview]
Message-ID: <20210607195430.48228-9-david@redhat.com> (raw)
In-Reply-To: <20210607195430.48228-1-david@redhat.com>
We allocate + initialize everything from scratch. In case enabling the
device fails, we free all memory resourcs.
