## Overview

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

i2c: viai2c-wmt: Fix clock leak in wmt_i2c_probe()

In wmt_i2c_probe(), i2c->clk is acquired using of_clk_get(). If any
subsequent operation fails or when the module is unloaded, the clock
reference count is never decremented via clk_put(), leading to a
resource leak.

Switch to devm_clk_get() so that the clock is automatically managed
and released.

## Affected

- `Linux >= 560746eb79d3124a278452c8dd968682b521cc82 < 5d476bb76b7d72d8b7ed04a9c614900b097e3af7`
- `Linux >= 560746eb79d3124a278452c8dd968682b521cc82 < 1875de656370c89b99a150d220df876288ee0344`
- `Linux >= 560746eb79d3124a278452c8dd968682b521cc82 < aaabefc79b0ff0018e8e3832169bbe359d0551fc`
