Subject: drivers/misc/mei/hbm.c:1212: bad if test ?

Hello there,

drivers/misc/mei/hbm.c:1212:46: warning: logical ‘and’ of mutually exclusive tests is always false [-Wlogical-op]

Source code is

        if (dev->hbm_state <= MEI_HBM_ENUM_CLIENTS &&
            dev->hbm_state>= MEI_HBM_STOPPED) {

Maybe better code

        if (dev->hbm_state <= MEI_HBM_ENUM_CLIENTS ||
            dev->hbm_state>= MEI_HBM_STOPPED) {


Regards

David Binderman
