PATCH 1/1 megaraid_mbox: remove scsi_assign_lock usage

also remove the adapter->host_lock alias for adapter->lock and remove some superflous locking aswell as removing the tiny locking wrappers for the EH routines.

ccsiss driver question

Does cciss driver support the ( deprecated) SCSI_IOCTL_SEND_COMMAND && SCSI_IOCTL_GET_IDLUN ioctls?
If not, is there a way to get these information from ccsiss driver without resorting to the corresponding sg driver device? Some code snippets which do this would be useful.

Also from userland, what would be an efficient way to get to the sg driver equivalent given an sd or a cciss device path?
( ie. other than enumerating each sg device and matching controller/target/lun values)

Thanks so much !!
