Subject: usb: xhci: dbc: remove redundant pointer dbc
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6c7dbe36198e23099209cb2938f9675849fdde68;p=linux.git

usb: xhci: dbc: remove redundant pointer dbc

Pointer dbc is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
variable 'dbc' set but not used [-Wunused-but-set-variable]
