Subject: [PATCH 13/20] ethernet: mellanox: convert tasklets to use new tasklet_setup() API
Date: Mon, 17 Aug 2020 13:54:27 +0530 [thread overview]
Message-ID: <20200817082434.21176-15-allen.lkml@gmail.com> (raw)
In-Reply-To: <20200817082434.21176-1-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.
