Description

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

iommu/mediatek: Remove clk_disable in mtk_iommu_remove

After the commit b34ea31fe013 ("iommu/mediatek: Always enable the clk on resume"), the iommu clock is controlled by the runtime callback. thus remove the clk control in the mtk_iommu_remove.

Otherwise, it will warning like:

echo 14018000.iommu > /sys/bus/platform/drivers/mtk-iommu/unbind
