From: Jérôme Pouiller <jerome.pouiller@xxxxxxxxxx> 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.
