Subject: [PATCH v3 21/35] dmaengine: ppc4xx: convert tasklets to use new tasklet_setup() API
Date: Mon, 31 Aug 2020 16:05:28 +0530	[thread overview]
Message-ID: <20200831103542.305571-22-allen.lkml@gmail.com> (raw)
In-Reply-To: <20200831103542.305571-1-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.
