If anyone has any objections, please let me know. ------------------ From: Bob Zhou [ Upstream commit 506c245f3f1cd989cb89811a7f06e04ff8813a0d ] In amdgpu_umc_bad_page_polling_timeout, the amdgpu_umc_handle_bad_pages will be run many times so that double free err_addr in some special case. So set the err_addr to NULL to avoid the warnings.
