From b08a26b87b2345b35eb5605446648a774cbb622d Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Mon, 28 Jul 2025 13:17:00 +0900 Subject: [PATCH] scsi: core: sysfs: Correct sysfs attributes access rights [ 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.
