Description
A vulnerability in the Linux kernel's ASoC Samsung i2s driver causes an imbalance in runtime power management due to the op_clk clock not being enabled during device probe. This leads to a warning during boot related to clock disablement. The issue is fixed by enabling op_clk in the probe function and disabling it in the remove function.
