Arnd Bergmann 9e6b4c36e9 dmaengine: remove debugfs #ifdef 
commit b3b180e735 upstream.

The ptdma driver has added debugfs support, but this fails to build
when debugfs is disabled:

drivers/dma/ptdma/ptdma-debugfs.c: In function 'ptdma_debugfs_setup':
drivers/dma/ptdma/ptdma-debugfs.c:93:54: error: 'struct dma_device' has no member named 'dbg_dev_root'
   93 |         debugfs_create_file("info", 0400, pt->dma_dev.dbg_dev_root, pt,
      |                                                      ^
drivers/dma/ptdma/ptdma-debugfs.c:96:55: error: 'struct dma_device' has no member named 'dbg_dev_root'
   96 |         debugfs_create_file("stats", 0400, pt->dma_dev.dbg_dev_root, pt,
      |                                                       ^
drivers/dma/ptdma/ptdma-debugfs.c:102:52: error: 'struct dma_device' has no member named 'dbg_dev_root'
  102 |                 debugfs_create_dir("q", pt->dma_dev.dbg_dev_root);
      |                                                    ^

Remove the #ifdef in the header, as this only saves a few bytes,
but would require ugly #ifdefs in each driver using it.
Simplify the other user while we're at it.

README 

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.
