Subject: [PATCH 2/4] mmc: sdhci: Rename sdhci_set_power() to sdhci_set_power_noreg()
Date: Wed, 5 Oct 2016 12:11:22 +0300 [thread overview]
Message-ID: <1475658684-32312-3-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1475658684-32312-1-git-send-email-adrian.hunter@intel.com>
Unlike other cases, sdhci_set_power() does not reflect the default
implementation of the ->set_power() callback. Rename it and create
sdhci_set_power() that is the default implementation.
