From: Sebastian Andrzej Siewior Date: Thu, 6 Sep 2012 18:11:09 +0000 (+0200) Subject: usb: gadget: start with libcomposite X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a84d9e5361bcfbff1c84481bd9c04fc58a56d83b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git usb: gadget: start with libcomposite This patch aims to be simple. It removes #include usbstribgs.c line from each gadget and creates libcomposite.ko which has only one member, that is usbstribgs.c.
