Merge tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi
Pull SCSI fixes from James Bottomley: "A bunch of fixes for aacraid, a set of coherency fixes that only affect non-coherent platforms and one coccinelle detected null check after use" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: libsas: align sata_device's rps_resp on a cacheline scsi: use dma_get_cache_alignment() as minimum DMA alignment scsi: dma-mapping: always provide dma_get_cache_alignment scsi: ufs: ufshcd: fix potential NULL pointer dereference in ufshcd_config_vreg scsi: aacraid: Prevent crash in case of free interrupt during scsi EH path scsi: aacraid: Perform initialization reset only once scsi: aacraid: Check for PCI state of device in a generic way
