From 2fa9bc98b5310b336ced0caa469a00f9e871758b Mon Sep 17 00:00:00 2001 From: Allen Pais Date: Mon, 31 Aug 2020 16:05:42 +0530 Subject: [PATCH] dmaengine: k3-udma: 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.
