The acpi_bind_one() error return path can be hit either on physical node
allocation failure or if the device being configured is already
associated with an ACPI node and its ACPI companion does not match the
one acpi_bind_one() is setting it up with. In both cases the error
return path is executed before DMA is configured for a device therefore
there is no need to call acpi_dma_deconfigure() on the function error
return path.
Furthermore, if acpi_bind_one() does configure DMA for a device (ie it
successfully executes acpi_dma_configure()) acpi_bind_one() always
completes execution successfully hence there is no need to add an exit
path to deconfigure the DMA set-up (ie by calling acpi_dma_deconfigure()).
Remove the misplaced acpi_dma_deconfigure() in acpi_bind_one() to
reinstate its correct error return path behaviour.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
