X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=dbbafe666c47d2e3d59cea66066f98c946a1e2de;p=openwrt%2Fstaging%2Fblogic.git

usb: gadget: uvc: Remove unneeded endpoint descriptor fields initialization

The streaming endpoint bandwidth parameters are computed are runtime
from module parameters. Remove the corresponding static initializers.
