Subject: [PATCH V6 05/14] scsi: sd_zbc: Fix sd_zbc_read_zoned_characteristics()
Date: Mon, 2 Oct 2017 16:15:26 +0900 [thread overview]
Message-ID: <20171002071535.8007-6-damien.lemoal@wdc.com> (raw)
In-Reply-To: <20171002071535.8007-1-damien.lemoal@wdc.com>
The three values starting at byte 8 of the Zoned Block Device
Characteristics VPD page B6h are 32 bits values, not 64bits. So use
get_unaligned_be32() to retrieve the values and not get_unaligned_be64()
Fixes: 89d947561077 ("sd: Implement support for ZBC devices")
