Subject: [PATCH v2 04/11] mmc: sdhci: at91: Use sdhci_set_power_and_voltage()
Date: Fri, 6 Mar 2020 18:44:06 +0100 [thread overview]
Message-ID: <20200306174413.20634-5-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200306174413.20634-1-nsaenzjulienne@suse.de>
The sdhci core provides a helper function with the same functionality as
this controller's set_power() callback. Use it instead.
