Subject: [PATCH 1/5] infiniband: bnxt_re: convert tasklets to use new tasklet_setup() API
Date: Mon, 17 Aug 2020 13:58:40 +0530	[thread overview]
Message-ID: <20200817082844.21700-2-allen.lkml@gmail.com> (raw)
In-Reply-To: <20200817082844.21700-1-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.
