If we assign 'epnum' during the declaration we can also avoid "ISO C90 forbids mixed declarations" issues. So it does looks like we can have our cake and eat it in this scenario. Fixes the following W=1 kernel build warning(s): drivers/usb/host/oxu210hp-hcd.c: In function ‘submit_async’: drivers/usb/host/oxu210hp-hcd.c:2040:19: warning: variable ‘qtd’ set but not used [-Wunused-but-set-variable] 2040 | struct ehci_qtd *qtd; | ^~~ Cc: Masahiro Yamada <yamada.masahiro@socionext.com> Cc: Rodolfo Giometti <giometti@linux.it> Cc: "Eurotech S.p.A" <info@eurtech.it> Signed-off-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20200702144625.2533530-24-lee.jones@linaro.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

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.
