static void omap_hsmmc_enable_sdio_irq(struct mmc_host *mmc, int enable)
Pandora_wl1251_init_card was used to do special pdata based setup of the sdio mmc interface. This does no longer work with v4.7 and later. A fix requires a device tree based mmc3 setup. Therefore we move the special setup to omap_hsmmc.c instead of calling some pdata supplied init_card function. The new code checks for a DT child node compatible to wl1251 so it will not affect other MMC3 use cases.
