[ Upstream commit a2f54ff15c3bdc0132e20aae041607e2320dbd73 ]
The SCSI sysfs attributes "supported_mode" and "active_mode" do not define a store method and thus cannot be modified. Correct the DEVICE_ATTR() call for these two attributes to not include S_IWUSR to allow write access as they are read-only.
