From 916fa097997a5e1b70768ce944de28e038d4bebf Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Fri, 23 Nov 2018 17:36:19 +0100 Subject: usb: composite: Move bitmap related operations to ./include/linux/bitmap.h The BITMAP related operations can now be moved to ./include/linux/bitmap.h file to mimic the Linux kernel directory tree. This change also allows to remove the lin_gadget_compat.h header file (which is a legacy code only for composite U-boot layer). It was also possible to remove #includes from several USB gadget drivers.
