[PATCH 0/2] DMA API usage fixes in gianfar

Hello.

This patch set fixes DMA API usage issues in gianfar ethernet driver
reported by the kernel w/ DMA API debug enabled.

There were even reports that the kernel sometimes oopsed in the past
because of kernel paging request handling failures, though it was likely
observed on some ancient versions. And while I personally doesn't have
any strong evidence of this, there's no reason to let these possible
failures live any longer.
