Subject: [PATCH 1/3] watchdog: iTCO_wdt: Export vendorsupport
Date: Tue, 25 Feb 2020 15:38:00 +0300	[thread overview]
Message-ID: <20200225123802.88984-2-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20200225123802.88984-1-mika.westerberg@linux.intel.com>

In preparation for making ->smi_res optional the iTCO_wdt driver needs
to know whether vendorsupport is being set to non-zero. For this reason
export the variable.
