From f2fa49988301965c4f8e7bfdf83145e677b1fbcc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Pali=20Roh=C3=A1r?= Date: Sat, 26 Dec 2020 19:12:11 +0100 Subject: [PATCH] usb: gadget: Do not export usbd_device_* arrays MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Each array is used only in one file (core.c or ep0.c). Move their content to correct file, mark them as static and do not export out of current file. This change allows to decrease size of u-boot.bin as more of those strings are not used.
