However, the commit missed to remove the NULL\nassignment of adap->rc that is now causing rc_free_device() to never be\ncalled on an allocated rc device.\n\nkmemleak reports following after e.g. dw-hdmi unbind:\n\nunreferenced object 0xffff00010ac10000 (size 4096):\n  comm \"kworker/u16:1\", pid 39, jiffies 4294897739\n  hex dump (first 32 bytes):\n    20 23 4b 0a 01 00 ff ff 08 00 c1 0a 01 00 ff ff   #K.............\n    08 00 c1 0a 01 00 ff ff 00 00 00 00 00 00 00 00  ................\n  backtrace (crc e11baccc):\n    kmemleak_alloc+0x38/0x44\n    __kmalloc_cache_noprof+0x4a8/0x5e0\n    rc_allocate_device+0x48/0x2a0\n    cec_allocate_adapter+0x3ac/0x800\n    dw_hdmi_cec_probe+0x264/0x634\n    platform_probe+0xc0/0x188\n    really_probe+0x4a4/0x8e0\n    __driver_probe_device+0x2f8/0x440\n    driver_probe_device+0x60/0x160\n    __device_attach_driver+0x1a0/0x2a0\n    bus_for_each_drv+0x100/0x1a0\n    __device_attach+0x174/0x350\n    device_initial_probe+0x90/0xb0\n    bus_probe_device+0x4c/0x120\n    device_add+0xdec/0x116c\n    platform_device_add+0x354/0x598\n\nRemove the assignment of adap->rc to NULL to let cec_delete_adapter()\nfree the allocated rc device after last user of the cec device exits to\nfix the kmemleak.",
