Subject: [PATCH v2 11/18] scsi: libsas: Add TMF handler exec complete callback
Date: Thu, 17 Feb 2022 23:42:39 +0800 [thread overview]
Message-ID: <1645112566-115804-12-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1645112566-115804-1-git-send-email-john.garry@huawei.com>
The pm8001 TMF handler has some special processing when the TMF completes,
so add a callback and fill it in for the pm8001 driver.
