From e8fa0ce65c58dbb60be279c4e33534650dcacc31 Mon Sep 17 00:00:00 2001 From: Pete Zaitcev Date: Mon, 23 Jul 2007 02:17:49 -0700 Subject: [PATCH] usblp: Make use of URB_FREE_BUFFER Employ the new API URB_FREE_BUFFER that we've got. There was talk of a combined constructor for this case, but apparently it's not happening, so just set the flag explicitly for now.
