Hi Romain,
Checkpatch gives some warnings you can fix related to NULL tests before
dma_pool_destroy(), and you changed indentation style in some of your
changes. Some times it is important to keep consistency within a file
even if the style is not the default. Please fix and resend.

The PCI pool API is deprecated. This commits replaces the PCI pool old API by the appropriated function with the DMA pool API.
