| H A D | sdhci-acpi.c | e28d6f04 Wed Jan 18 03:46:18 CST 2017 Zhang Rui <rui.zhang@intel.com> mmc: sdhci-acpi: support deferred probe
With commit 67bf5156edc4 ("gpio / ACPI: fix returned error from
acpi_dev_gpio_irq_get()"), mmc_gpiod_request_cd() returns -EPROBE_DEFER if
GPIO is not ready when sdhci-acpi driver is probed, and sdhci-acpi driver
should be probed again later in this case.
This fixes an order issue when both GPIO and sdhci-acpi drivers are built
as modules.
