--------------------------------

[ Upstream commit 142e821f ]

A clk, prepared and enabled in mtk_iommu_v1_hw_init(), is not released in
the error handling path of mtk_iommu_v1_probe().

Add the corresponding clk_disable_unprepare(), as already done in the
remove function.

Fixes: b17336c5 ("iommu/mediatek: add support for mtk iommu generation one HW")
