Subject: [PATCH 4/8] scsi: isci: convert tasklets to use new tasklet_setup() API
Date:   Mon, 17 Aug 2020 14:24:05 +0530
Message-Id: <20200817085409.25268-5-allen.cryptic@gmail.com>
In-Reply-To: <20200817085409.25268-1-allen.cryptic@gmail.com>
References: <20200817085409.25268-1-allen.cryptic@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Allen Pais <allen.lkml@gmail.com>

In preparation for unconditionally passing the
struct tasklet_struct pointer to all tasklet
callbacks, switch to using the new tasklet_setup()
and from_tasklet() to pass the tasklet pointer explicitly.
