A fix is available — apply it.

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

media: i2c/tw9906: Fix potential memory leak in tw9906_probe()

In one of the error paths in tw9906_probe(), the memory allocated in v4l2_ctrl_handler_init() and v4l2_ctrl_new_std() is not freed. Fix that by calling v4l2_ctrl_handler_free() on the handler in that error path.
