Description

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

i2c: tegra: fix pm_runtime leak on mutex_lock failure

If tegra_i2c_mutex_lock() fails, the function returns without calling pm_runtime_put(), leaking the runtime PM reference acquired by the preceding pm_runtime_get_sync(). This prevents the device from ever entering runtime suspend.

Add the missing pm_runtime_put() before returning on lock failure.
