From 77a4f4f74eecaba5357dbc188dbe935aa9cf8fcf Mon Sep 17 00:00:00 2001 From: Allen Pais Date: Mon, 31 Aug 2020 16:05:21 +0530 Subject: dmaengine: mmp: convert tasklets to use new tasklet_setup() API 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.
