Description

In the Linux kernel, the following vulnerability has been resolved:

scsi: ufs: exynos: Disable iocc if dma-coherent property isn't set

If dma-coherent property isn't set then descriptors are non-cacheable
and the iocc shareability bits should be disabled. Without this UFS can
end up in an incompatible configuration and suffer from random cache
related stability issues.
