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:  AssertionError: unreferenced object 0xffff888107362160 (size 16):   comm "python3", pid 277, jiffies 4294832798 (age 20.722s)   hex dump (first 16 bytes):     00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................   backtrace:     [<00000000abe7d67c>] __kmalloc_node+0x44/0x1b0     [<000000008a725aac>] kvmalloc_node+0x34/0x180     [<000000009a53cd11>] v4l2_ctrl_handler_init_class+0x11d/0x180 [videodev]     [<0000000055b46db0>] ov5675_probe+0x38b/0x897 [ov5675]     [<00000000153d886c>] i2c_device_probe+0x28d/0x680     [<000000004afb7e8f>] really_probe+0x17c/0x3f0     [<00000000ff2f18e4>] __driver_probe_device+0xe3/0x170     [<000000000a001029>] driver_probe_device+0x49/0x120     [<00000000e39743c7>] __device_attach_driver+0xf7/0x150     [<00000000d32fd070>] bus_for_each_drv+0x114/0x180     [<000000009083ac41>] __device_attach+0x1e5/0x2d0     [<0000000015b4a830>] bus_probe_device+0x126/0x140     [<000000007813deaf>] device_add+0x810/0x1130     [<000000007becb867>] i2c_new_client_device+0x386/0x540     [<000000007f9cf4b4>] of_i2c_register_device+0xf1/0x110     [<00000000ebfdd032>] of_i2c_notify+0xfc/0x1f0  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.
