From b282a118eb4ecb5d32eb022f4bed929531d9925b Mon Sep 17 00:00:00 2001 From: Krzysztof Opasiak Date: Fri, 2 Dec 2016 18:42:22 +0100 Subject: usbip: vudc: Refactor init_vudc_hw() to be more obvious Current implementation of init_vudc_hw() adds ep0 to ep_list and then after looping through all endpoints removes it from that list. As this may be misleading let's refactor this function and avoid adding and removing ep0 to eplist and place it immediately in correct place. In addition let's remove redundant 0 assignments as ep array is zeroed during allocation.
