Seems the problem is caused by rtl92c_dm_*() casting .priv to "struct rtl_pci_priv", while it is "struct rtl_usb_priv".
Those routines are shared by rtl8192ce and rtl8192cu, thus we need to make that difference in cast to be immaterial. I think we need to move "struct bt_coexist_info" to the beginning of both rtlpci_priv and rtl_usb_priv. Then it should not matter.
I do not have a gcc version new enough to turn KASAN testing on, thus the attached patch is only compile tested. Does it fix the problem?
