Subject: [PATCH v2 1/2] rtc: wilco-ec: Remove yday and wday calculations
Date:   Mon, 16 Sep 2019 12:12:15 -0600
Message-Id: <20190916181215.501-1-ncrews@chromium.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The tm_yday and tm_wday fields are not used by userspace,
so since they aren't needed within the driver, don't
bother calculating them. This is especially needed since
the rtc_year_days() call was crashing if the HW returned
an invalid time.
