Subject: [PATCH v2 04/15] scsi: ufs: ufs-exynos: simplify drv_data retrieval
Date: Wed, 14 Jul 2021 16:11:20 +0900	[thread overview]
Message-ID: <20210714071131.101204-5-chanho61.park@samsung.com> (raw)
In-Reply-To: <20210714071131.101204-1-chanho61.park@samsung.com>

The compatible field of exynos_ufs_drv_data is not necessary because
of_device_id already has it. Thus, we don't need it anymore and we can
get drv_data by device_get_match_data.
