SubjectRe: [PATCH] scsi: ufs: fix integer type usage in uapi header


> We get a warning from 'make headers_check' about a newly introduced
> usage of integer types in the scsi/scsi_bsg_ufs.h uapi header:
> usr/include/scsi/scsi_bsg_ufs.h:18: found __[us]{8,16,32,64} type without #include <linux/types.h>

Applied to 4.20/scsi-queue, thank you!
