Subject: [PATCH v5 01/19] crypto: amcc: convert tasklets to use new tasklet_setup() API
Date:   Mon,  8 Feb 2021 15:12:20 +0530
Message-Id: <20210208094238.571015-2-allen.lkml@gmail.com>

From: Allen Pais <apais@linux.microsoft.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.
