Subject: usb: dwc3: gadget: Remove redundant check
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=110381e11b5fbf84bc0994d4c3f4629bc362ab4c;p=openwrt%2Fstaging%2Fblogic.git

usb: dwc3: gadget: Remove redundant check

dwc3_gadget_init_hw_endpoints calls dwc3_alloc_trb_pool only if epnum is not
equal to 0 or 1. Hence, rechecking it in the called function is redundant.
