* [PATCH 04/10] sound: riptide: convert tasklets to use new tasklet_setup() API
From: Allen Pais @ 2020-08-17 8:56 UTC (permalink / raw)
To: perex, tiwai, clemens, o-takashi, timur, nicoleotsuka, Xiubo.Lee

In-Reply-To: <20200817085703.25732-1-allen.cryptic@gmail.com>
From: Allen Pais <allen.lkml@gmail.com>
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.

* [PATCH 6/8] scsi: mvsas: convert tasklets to use new tasklet_setup() API
From: Allen Pais @ 2020-08-17 8:54 UTC (permalink / raw)

In-Reply-To: <20200817085409.25268-1-allen.cryptic@gmail.com>
From: Allen Pais <allen.lkml@gmail.com>
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.

Commit 12cc923f1ccc ("tasklet: Introduce new initialization API")'
introduced a new tasklet initialization API. This series converts
all the scsi drivers to use the new tasklet_setup() API
Allen Pais (8):
scsi: aic94xx: convert tasklets to use new tasklet_setup() API
scsi: esas2r: convert tasklets to use new tasklet_setup() API
scsi: ibmvscsi: convert tasklets to use new tasklet_setup() API
scsi: isci: convert tasklets to use new tasklet_setup() API
scsi: megaraid: convert tasklets to use new tasklet_setup() API
scsi: mvsas: convert tasklets to use new tasklet_setup() API
scsi: pm8001: convert tasklets to use new tasklet_setup() API
scsi: pmcraid: convert tasklets to use new tasklet_setup() API

In-Reply-To: <20200817085409.25268-1-allen.cryptic@gmail.com>
From: Allen Pais <allen.lkml@gmail.com>
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.
