Move the definition of this function from a public into a private header
file since it is only used inside the UFS core.

You didn't move this function to drivers/ufs/core/ufshcd-priv.h,
It is used by the drivers/ufs/core/ufs-sysfs.c. Otherwise, there is no
problem in compiling.


Kind regards,
Bean

Hmm ... it is not clear why you wrote the above? I think that the diff 
clearly shows that ufs_is_valid_unit_desc_lun() is moved into 
drivers/scsi/ufs/ufshcd-priv.h.

Thanks,

Bart.
