In the Linux kernel definitions of data structures should occur in .c
files. Hence move the exynos7_uic_attr definition from a .h into a .c
file. Additionally, declare exynos_ufs_drvs static. This patch fixes the
following two sparse warnings:
drivers/scsi/ufs/ufs-exynos.h:248:28: warning: symbol 'exynos_ufs_drvs' was not declared. Should it be static?
drivers/scsi/ufs/ufs-exynos.h:250:28: warning: symbol 'exynos7_uic_attr' was not declared. Should it be static?

Just for the subject tag consistency, can add subsystem name , scsi: ufs:
<driver_name>
Rest looks good.

Martin Petersen, the SCSI maintainer will add the "scsi: " prefix to the
subject before applying this patch. So you want me to change the subject
prefix from "ufs-exynos: " into "ufs: ufs-exynos: "?
Anyway, thanks for the review.
Bart.

Don't worry about it, I'll fix that up.
