Do you agree with changing switch (state) into switch ((int)state) ?
Without that additional change gcc reports the following warning:
drivers/scsi/scsi_sysfs.c: In function ?store_state_field?:
drivers/scsi/scsi_sysfs.c:640:2: warning: case value ?0? not in
enumerated type ?enum scsi_device_state? [-Wswitch]
Either that, or add a SDEV_INVALID_STATE = 0 value to the enum. That
variant seems a little more elegant.
Hmm ... I think the second option would require to add an additional
case in sdev_set_state() to avoid a compiler warning. This is something
James objected against (on June 24, see also
http://thread.gmane.org/gmane.linux.scsi/82572/focus=82576).
