From: David Brownell Date: Tue, 19 Aug 2008 00:43:25 +0000 (-0700) Subject: usb gadget: link fixes for storage gadget X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=352e2b961c885b98065c402e2ad85057d0a334b2;p=linux-beck.git usb gadget: link fixes for storage gadget Change how the file storage gadget driver builds: don't use separate compilation, since it works poorly when key parts are library code (with init sections etc). Instead be as close as we can to "gcc --combine ...".
