The patch titled sdio: add MMC_QUIRK_LENIENT_FN0 has been removed from the -mm tree. Its filename was sdio-add-mmc_quirk_lenient_fn0.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: sdio: add MMC_QUIRK_LENIENT_FN0 From: Ohad Ben-Cohen <ohad@xxxxxxxxxx> Normally writes to SDIO function 0 outside the vendor specific CCCR registers are prohibited. To support embedded devices that require writes to SDIO function 0 outside this range (e.g. TI WL127x embedded sdio wifi device), MMC_QUIRK_LENIENT_FN0 is introduced. A card quirks field is added to `struct mmc_card' to support non-standard devices (e.g. embedded sdio devices).
