Subject: [PATCH v2 2/6] mmc: sdhci: Deduplicate sdhci_get_cd_nogpio()
Date: Wed, 13 Oct 2021 23:17:19 +0300	[thread overview]
Message-ID: <20211013201723.52212-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20211013201723.52212-1-andriy.shevchenko@linux.intel.com>

The analogue of the sdhci_get_cd_nogpio() is used in the sdhci-pci-core
and sdhci-acpi modules. Deduplicate it by moving to sdhci and exporting.
