From: Felipe Balbi Date: Tue, 12 Apr 2016 13:42:43 +0000 (+0300) Subject: usb: dwc3: gadget: pass dep as argument to endpoint command X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2cd4718d0bbe1906fcf517f0b254fbd7c072383a;p=linux-beck.git usb: dwc3: gadget: pass dep as argument to endpoint command In all call sites of dwc3_send_gadget_ep_cmd() we already had a valid dep pointer, so instead of passing dwc and dep->number, which would be used to fetch the same pointer we already had, just pass dep directly. In other words, we're changing: struct dwc3_ep *dep = dwc[dep->number]; to just passing struct dwc3_ep *dep as argument.
