Subject: [PATCH 3/3] wilc1000: use devm_clk_get_optional()
Date: Fri, 6 Aug 2021 11:12:29 +0300	[thread overview]
Message-ID: <20210806081229.721731-4-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <20210806081229.721731-1-claudiu.beznea@microchip.com>

Use devm_clk_get_optional() for rtc clock: it simplifies a bit
the code.
