Description
In the Linux kernel, the following vulnerability has been resolved:
media: ov5675: Fix memleak in ov5675_init_controls()
There is a kmemleak when testing the media/i2c/ov5675.c with bpf mock device:

ov5675_init_controls() won't clean all the allocated resources in fail path, which may causes the memleaks. Add v4l2_ctrl_handler_free() to prevent memleak.
