Subject: [PATCH v3 14/14] rtc: rx8010: use range checking provided by core RTC code
Date: Mon, 14 Sep 2020 17:46:01 +0200 [thread overview]
Message-ID: <20200914154601.32245-15-brgl@bgdev.pl> (raw)
In-Reply-To: <20200914154601.32245-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
We don't need to check the time range manually in set_time(), we can
use range_min and range_max exposed by struct rtc_device.
