[PATCH v6 00/15] Replace PCI pool by DMA pool API

[PATCH v6 00/15] Replace PCI pool by DMA pool API

[Romain Perier]

The current PCI pool API are simple macro functions direct expanded to
the appropriate dma pool functions. The prototypes are almost the same
and semantically, they are very similar. I propose to use the DMA pool
API directly and get rid of the old API.

This set of patches, replaces the old API by the dma pool API
and remove the defines.

Changes in v6:
- Fixed an issue reported by kbuild test robot about changes in DAC960
- Removed patches 15/19,16/19,17/19,18/19. They have been merged by Greg
- Added Acked-by Tags

Changes in v5:
- Re-worded the cover letter (remove sentence about checkpatch.pl)
- Rebased series onto next-20170308
- Fix typos in commit message
- Added Acked-by Tags

Changes in v4:
- Rebased series onto next-20170301
- Removed patch 20/20: checks done by checkpath.pl, no longer required.
  Thanks to Peter and Joe for their feedbacks.
- Added Reviewed-by tags

Changes in v3:
- Rebased series onto next-20170224
- Fix checkpath.pl reports for patch 11/20 and patch 12/20
- Remove prefix RFC
Changes in v2:
- Introduced patch 18/20
- Fixed cosmetic changes: spaces before brace, live over 80 characters
- Removed some of the check for NULL pointers before calling dma_pool_destroy
- Improved the regexp in checkpatch for pci_pool, thanks to Joe Perches
- Added Tested-by and Acked-by tags

Changes look ok, and I've tested them here as well.

[PATCH v6 09/15] scsi: csiostor: Replace PCI pool old API

[Romain Perier]

The PCI pool API is deprecated. This commit replaces the PCI pool old
API by the appropriate function with the DMA pool API. It also updates
the name of some variables and the content of comments, accordingly.

[PATCH v6 11/15] scsi: megaraid: Replace PCI pool old API

[Romain Perier]

The PCI pool API is deprecated. This commit replaces the PCI pool old
API by the appropriate function with the DMA pool API.

[PATCH v6 13/15] scsi: mvsas: Replace PCI pool old API

[Romain Perier]

The PCI pool API is deprecated. This commit replaces the PCI pool old
API by the appropriate function with the DMA pool API.

[PATCH v6 14/15] scsi: pmcraid: Replace PCI pool old API
