imx_shutdown() calls imx_disable_dma if .dma_is_enabled. So after imx_shudown() completes, .dma_is_enabled is zero. For this reason .dma_is_enabled is also zero when imx_startup() is called. So the check for this variable being zero can be dropped.

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.
