scsi: ufs: exynos: Fix programming of HCI_UTRL_NEXUS_TYPE stable inclusion from stable-6.6.105 commit 01aad16c2257 category: bugfix issue: #223 CVE: CVE-2025-39788 Signed-off-by: zxl <1554188414@qq.com> ------------------------------- scsi: ufs: exynos: Fix programming of HCI_UTRL_NEXUS_TYPE On Google gs101, the number of UTP transfer request slots (nutrs) is 32, and in this case the driver ends up programming the UTRL_NEXUS_TYPE incorrectly as 0. This is because the left hand side of the shift is 1, which is of type int, i.e. 31 bits wide. Shifting by more than that width results in undefined behaviour. Fix this by switching to the BIT() macro, which applies correct type casting as required. This ensures the correct value is written to UTRL_NEXUS_TYPE (0xffffffff on gs101), and it also fixes a UBSAN shift warning: UBSAN: shift-out-of-bounds in drivers/ufs/host/ufs-exynos.c:1113:21 shift exponent 32 is too large for 32-bit type 'int' For consistency, apply the same change to the nutmrs / UTMRL_NEXUS_TYPE write.

scsi: ufs: Split the drivers/scsi/ufs directory Split the drivers/scsi/ufs directory into 'core' and 'host' directories under the drivers/ufs/ directory. Move shared header files into the include/ufs/ directory. This separation makes it clear which header files UFS drivers are allowed to include (include/ufs/*.h) and which header files UFS drivers are not allowed to include (drivers/ufs/core/*.h). Update the MAINTAINERS file. Add myself as a UFS reviewer.
