From e0a739f48ea33ae939009f2db28091e66024dbf9 Mon Sep 17 00:00:00 2001 From: Allen Pais Date: Wed, 16 Sep 2020 11:45:19 +0530 Subject: staging: wlan-ng: 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.
