From: Bui Quang Minh <minhquangbui99@gmail.com> commit e90cfa813da7a527785033a0b247594c2de93dd8 upstream. This error path err_add_pdata: for (i = 0; i < mod_data.num; i++) kfree(dum[i]); can be triggered when not all dum's elements are initialized. Fix this by initializing all dum's elements to NULL.
