38 Patches, two adding support for new devices (ufs, mvsas), a major set of six fixes in lpfc plus a huge chunk removal in pmcraid to get rid of a driver specific ioctl and a major rework of aha152x to get rid of the scsi_pointer. The rest are minor fixes and obvious changes including several spelling updates.
