The ffs_data_clear() called in ffs_data_reset()\nsets ffs->epfiles to NULL before resetting ffs->eps_count to 0, leading\nto a NULL pointer dereference when accessing epfile->ep in\nffs_func_eps_enable() after successful usb_ep_enable().\n\nThe ffs->epfiles pointer is set to NULL in both ffs_data_clear() and\nffs_data_close() functions, and its modification is protected by the\nspinlock ffs->eps_lock.
