Subject: nvme: report the DPOFUA in MODE_SENSE
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=908517684807f3b3d93893da78c7906f5ff2c49b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

nvme: report the DPOFUA in MODE_SENSE

NVMe device always support the FUA bit, and the SCSI translations
accepts the DPO bit, which doesn't have much of a meaning for us.
