Subject: mpt3sas: Fix initial Reference tag field for 4K PI drives.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=648512ccd7d42ccf761f515b7c0cb456a48c477a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mpt3sas: Fix initial Reference tag field for 4K PI drives.

Modified driver code to use scsi_prot_ref_tag() API instead of
scsi_get_lba(), while initializing reference tag field in the CDB.
