Subject: [PATCH 05/12] OvmfPkg/VirtioSerialDxe: use TPL_NOTIFY
RH-Author: Gerd Hoffmann <kraxel@redhat.com>
RH-MergeRequest: 39: ArmVirt: add VirtioSerialDxe to ArmVirtQemu builds
RH-Jira: RHEL-643
RH-Acked-by: Laszlo Ersek <lersek@redhat.com>
RH-Commit: [5/6] 08998538804a8d62903e44e716bcafd9674d208f (kraxel/centos-edk2)
Apparently TPL_CALLBACK is too low, code runs into an ASSERT
complaining the new TPL is lower than the old TPL.
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
(cherry picked from commit 4e5a804222415ec7b2bec90ea0300b8a9f60f131)
