Title
media: bcm2835-unicam: Fix asc leaked in error/remove path
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: bcm2835-unicam: Fix asc leaked in error/remove path
v4l2_async_nf_add_fwnode_remote() allocates the asc, which is freed when
v4l2_async_nf_cleanup() is called.
Call v4l2_async_nf_cleanup() properly in the driver paths.
Discovered with kmemleak after rmmod:
unreferenced object 0xffff000084526b80 (size 64):
comm "modprobe", pid 185, jiffies 4295013512
