Description
A resource leak vulnerability in the Linux kernel's viai2c-wmt driver was fixed by changing clock management in the wmt_i2c_probe() function. The issue involved the clock reference count not being decremented properly, leading to a clock leak. The fix switches to using devm_clk_get() to ensure automatic clock release.
