Commit af566a0be6 ("usb: dwc3: omap: get rid of dma_status") rendered
reading DMA status from the H/W even more redundant. The variable hasn't
been read/used since 2016. Remove the set but unused variable and the call
which populates it.
Fixes the following W=1 warning:
drivers/usb/dwc3/dwc3-omap.c: In function ‘dwc3_omap_probe’:
drivers/usb/dwc3/dwc3-omap.c:460:8: warning: variable ‘reg’ set but not used [-Wunused-but-set-variable]
460 | u32 reg;

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.
