From: Al Viro <v...@zeniv.linux.org.uk> Passing a physical address to free_pages() is a bad idea. config_params->fault_pxl.fpc_table_addr is set to virt_to_phys() of __get_free_pages() return value; what we should pass to free_pages() is its phys_to_virt(). ccdc_close() does that properly, but ccdc_update_raw_params() doesn't.
