Subject:    [PATCH v3 17/35] dmaengine: mxs-dma: convert tasklets to use new tasklet_setup() API
From:       Allen Pais <allen.lkml () gmail ! com>

Message-ID: 20200831103542.305571-18-allen.lkml () gmail ! com
[Download RAW message or body]

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.
