CVE-2026-68220

media: nxp: imx8-isi: Add missing v4l2_subdev_cleanup() in crossbar and pipe

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

media: nxp: imx8-isi: Add missing v4l2_subdev_cleanup() in crossbar and pipe

Both mxc_isi_crossbar_init() and mxc_isi_pipe_init() call
v4l2_subdev_init_finalize() which allocates the subdev active state,
but neither mxc_isi_crossbar_cleanup() nor mxc_isi_pipe_cleanup()
calls v4l2_subdev_cleanup() to free it.

This causes a memory leak on every rmmod, reported by kmemleak:

  unreferenced object 0xffff0000d06fc800 (size 192):
    comm "(udev-worker)", pid 254, jiffies 4294913455
    backtrace (crc 36eeae58):
      kmemleak_alloc+0x34/0x40
      __kvmalloc_node_noprof+0x5f8/0x7d8
      __v4l2_subdev_state_alloc+0x1fc/0x30c
      __v4l2_subdev_init_finalize+0x178/0x368

Add the missing v4l2_subdev_cleanup() calls before media_entity_cleanup()
in both crossbar and pipe cleanup paths.
