modpost: remove unneeded .symbol_white_list initializers
The ->symbol_white_list field is referenced in secref_whitelist(), only when 'fromsec' is data_sections. /* Check for pattern 2 */ if (match(tosec, init_exit_sections) && match(fromsec, data_sections) && match(fromsym, mismatch->symbol_white_list)) return 0; If .fromsec is not data sections, the .symbol_white_list member is not used by anyone.
