Subject: [PATCH v4 17/19] crypto: s5p: convert tasklets to use new tasklet_setup() API
Date: Thu, 21 Jan 2021 10:11:24 +0530	[thread overview]
Message-ID: <20210121044126.152274-18-allen.lkml@gmail.com> (raw)
In-Reply-To: <20210121044126.152274-1-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.
