From: Sebastian Andrzej Siewior Date: Sun, 23 Dec 2012 20:09:58 +0000 (+0100) Subject: usb: gadget: move source sink's config descriptor out of f_sourcesink X-Git-Tag: firefly_0821_release~3680^2~1079^2~43^2~38 X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=eeae54075ce3491968e9282cbb44f6a06b306b66;p=firefly-linux-kernel-4.4.55.git usb: gadget: move source sink's config descriptor out of f_sourcesink f_sourcesink should only include the bare function but it also includes the config descriptor. This patch moves the config descriptor into zero.c, the only user of this function.
