Subject: [PATCH v3 10/17] scsi: ufs: ufs-exynos: support custom version of ufs_hba_variant_ops
Date: Fri, 17 Sep 2021 15:54:29 +0900	[thread overview]
Message-ID: <20210917065436.145629-11-chanho61.park@samsung.com> (raw)
In-Reply-To: <20210917065436.145629-1-chanho61.park@samsung.com>

By default, ufs_hba_exynos_ops will be used but this patch supports to
use custom version of ufs_hba_variant_ops because some variants of
exynos-ufs will use only few callbacks.
