It's pointless to enable the chip back if the DMA setup procedure fails, since we'll disable it on the next transfer anyway. For the same reason We don't do that in case of a failure detected in any other methods called from the transfer_one() method. While at it consider any non-zero value returned from the dma_setup callback to be erroneous as it's supposed to be in the kernel.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
