Subject: [PATCH v2 06/20] ethernet: chelsio: convert tasklets to use new tasklet_setup() API
Date: Wed, 9 Sep 2020 14:14:56 +0530 [thread overview]
Message-ID: <20200909084510.648706-7-allen.lkml@gmail.com> (raw)
In-Reply-To: <20200909084510.648706-1-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.
