Subject: [PATCH v2 05/22] watchdog: ziirave_wdt: Log bootloader/firmware info during probe
Date: Mon, 12 Aug 2019 13:08:49 -0700
Message-ID: <20190812200906.31344-6-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190812200906.31344-1-andrew.smirnov@gmail.com>

Log bootloader/firmware info during probe. This information is
available via sysfs already, but it's really helpful to have this in
kernel log during startup as well.
