Subject: [PATCH 2/4] tty: atmel_serial: convert tasklets to use new tasklet_setup() API
Date: Mon, 17 Aug 2020 14:29:19 +0530	[thread overview]
Message-ID: <20200817085921.26033-3-allen.cryptic@gmail.com> (raw)
In-Reply-To: <20200817085921.26033-1-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.
