Subject: [PATCH 4.9 17/42] mmc: fix compilation of user API

From: Jérôme Pouiller <jerome.pouiller@...abs.com>

commit 83fc5dd57f86c3ec7d6d22565a6ff6c948853b64 upstream.

The definitions of MMC_IOC_CMD  and of MMC_IOC_MULTI_CMD rely on
MMC_BLOCK_MAJOR:

    #define MMC_IOC_CMD       _IOWR(MMC_BLOCK_MAJOR, 0, struct mmc_ioc_cmd)
    #define MMC_IOC_MULTI_CMD _IOWR(MMC_BLOCK_MAJOR, 1, struct mmc_ioc_multi_cmd)

However, MMC_BLOCK_MAJOR is defined in linux/major.h and
linux/mmc/ioctl.h did not include it.
