Summary
In the Linux kernel, the following vulnerability has been resolved: media: v4l2-subdev: Fix alloc failure check in v4l2_subdev_call_state_try() v4l2_subdev_call_state_try() macro allocates a subdev state with __v4l2_subdev_state_alloc(), but does not check the returned value. If __v4l2_subdev_state_alloc fails, it returns an ERR_PTR, and that would cause v4l2_subdev_call_state_try() to crash. Add proper error handling to v4l2_subdev_call_state_try().
