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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
