From 6c1fd9ad2c5b722cf4b6c300ea3660ba324dae98 Mon Sep 17 00:00:00 2001 From: Allen Pais Date: Mon, 31 Aug 2020 16:05:40 +0530 Subject: [PATCH] dmaengine: plx_dma: 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.
