[PATCH] clk: mediatek: Fix error handling in runtime PM setup

[Stephen Boyd]

Quoting Haotian Zhang (2025-11-23 08:43:15)
> devm_pm_runtime_enable() can fail due to memory allocation. The current
> code ignores its return value, and when pm_runtime_resume_and_get() fails,
> it returns directly without unmapping the shared_io region.
> 
> Add error handling for devm_pm_runtime_enable(). Reorder cleanup labels
> to properly unmap shared_io on pm_runtime_resume_and_get() failure.
