From 1a12af1a751311e129ff8e8ca18f83613b78a83c Mon Sep 17 00:00:00 2001 From: Michal Nazarewicz Date: Tue, 12 Jun 2012 12:42:17 +0200 Subject: [PATCH] usb: gadget: mass_storage: remove unused options This commit removes thread_name and lun_name_format fields from the fsg_config structure. Those fields are not used by any in-tree code and their usefulness is rather theoretical.
