Subject: [PATCH] scsi: dc395x: Convert timers to use timer_setup()
Date: Wed, 18 Oct 2017 13:33:14 -0700 [thread overview]
Message-ID: <20171018203314.GA144614@beast> (raw)
In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.
Signed-off-by: Kees Cook <keescook@chromium.org>
Reviewed-by: Martin K. Petersen <martin.petersen@oracle.com>

This is a resend to tglx, with Reviews/Acks. Martin Petersen suggested
that scsi timer conversions should go via the timer tree.
