the DMA_SUCCESS is a misnomer as dmaengine indicates the transfer is complete and
gives no guarantee of the transfer success. Hence we should use DMA_COMPLTE
instead of DMA_SUCCESS

This patch adds support for suspend/resume functionality to the cppi41
DMA driver. The steps necessary to make the system resume properly were
figured out by trial-and-error. The code as it stands now is the
minimum that has to be done to put the musb host system on an AM33xx
system into an operable state after resume.

dst_addr_width and src_addr_width should be a power of 2. Currently the
driver checks, that they both lie between 1 and 8 and that they are equal
to 1 or even. This however leaves an invalid value of 6 uncaught. Use an
explicit power of 2 check instead.

Instead of passing around struct plafform_device, use struct device and
save one level of dereferencing. This affects the following functions:
* cppi41_add_chans
* purge_descs
* deinit_cpii41
* init_descs
* init_cppi41
* cppi_glue_infos
It's just a cosmetic cleanup that makes the code more readable.

Pull SCSI target fixes from Nicholas Bellinger:
"Here are the outstanding target fixes queued up for v3.12-rc4 code.
The highlights include:
- Make vhost/scsi tag percpu_ida_alloc() use GFP_ATOMIC
- Allow sess_cmd_map allocation failure fallback to use vzalloc
- Fix COMPARE_AND_WRITE se_cmd->data_length bug with FILEIO backends
- Fixes for COMPARE_AND_WRITE callback recursive failure OOPs + non
zero scsi_status bug
- Make iscsi-target do acknowledgement tag release from RX context
- Setup iscsi-target with extra (cmdsn_depth / 2) percpu_ida tags
Also included is a iscsi-target patch CC'ed for v3.10+ that avoids
legacy wait_for_task=true release during fast-past StatSN
acknowledgement, and two other SRP target related patches that address
long-standing issues that are CC'ed for v3.3+.
Extra thanks to Thomas Glanzmann for his testing feedback with
COMPARE_AND_WRITE + EXTENDED_COPY VAAI logic"
* git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
iscsi-target; Allow an extra tag_num / 2 number of percpu_ida tags
iscsi-target: Perform release of acknowledged tags from RX context
iscsi-target: Only perform wait_for_tasks when performing shutdown
target: Fail on non zero scsi_status in compare_and_write_callback
target: Fix recursive COMPARE_AND_WRITE callback failure
target: Reset data_length for COMPARE_AND_WRITE to NoLB * block_size
ib_srpt: always set response for task management
target: Fall back to vzalloc upon ->sess_cmd_map kzalloc failure
vhost/scsi: Use GFP_ATOMIC with percpu_ida_alloc for obtaining tag
ib_srpt: Destroy cm_id before destroying QP.
target: Fix xop->dbl assignment in target_xcopy_parse_segdesc_02

Pull CIFS fixes from Steve French:
"Small set of cifs fixes. Most important is Jeff's fix that works
around disconnection problems which can be caused by simultaneous use
of user space tools (starting a long running smbclient backup then
doing a cifs kernel mount) or multiple cifs mounts through a NAT, and
Jim's fix to deal with reexport of cifs share.
I expect to send two more cifs fixes next week (being tested now) -
fixes to address an SMB2 unmount hang when server dies and a fix for
cifs symlink handling of Windows "NFS" symlinks"
* 'for-linus' of git://git.samba.org/sfrench/cifs-2.6:
