Subject: [PATCH 20/35] dma: pl330: convert tasklets to use new tasklet_setup() API
Date: Tue, 18 Aug 2020 14:36:23 +0530	[thread overview]
Message-ID: <20200818090638.26362-21-allen.lkml@gmail.com> (raw)
In-Reply-To: <20200818090638.26362-1-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.
