CVE-2026-80650

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

media: atomisp: gc2235: fix UAF and memory leak

gc2235_probe() handles its error paths incorrectly.

If media_entity_pads_init() fails, gc2235_remove() is called, which
tears down the subdev and frees dev, but then still falls through to
atomisp_register_i2c_module(). This results in use-after-free.

If atomisp_register_i2c_module() fails, the media entity and control
handler are left initialized and dev is leaked.

gc2235_remove() unconditionally calls media_entity_cleanup() and
v4l2_ctrl_handler_free(), but these are not initialized at every
error path in gc2235_probe().

Replace gc2235_remove() calls in the probe error paths with explicit
unwind labels that free only the resources initialized at each point
of failure, in reverse order of initialization.
