For move_block_from_dma, there is only one call and the return value is dropped, so it need not be unsigned. For labpc_eeprom_write, there is only one call and the result is stored in a signed variable, so again the unsigned return type is not necessary. A sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @exists@ identifier f; constant C; @@ unsigned f(...) { <+... * return -C; ...+> } // Signed-off-by: Julia Lawall Signed-off-by: Greg Kroah-Hartman Ś!4Mž
