Description

In the Linux kernel, the following vulnerability has been resolved: phy: sunplus: fix error handling in sp_uphy_init() Fix the error paths of sp_uphy_init() to undo exactly what each stage did: return directly if clk_prepare_enable() fails, release only the clock if reset_control_deassert() fails, and jump to err_reset if update_disc_vol() fails so the clock and reset are not leaked.
