From 2c12ff039ca6e36c8c2025befcda3d91fbf47dcd Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 4 Dec 2015 01:36:36 +0100 Subject: usb: s3c-otg: Split private bits from s3c_udc.h Most of the functions are local to the s3c_udc driver, remove them from the s3c_udc.h header to stop those bits from propagating all over the place. Instead, move all the private stuff into new private s3c_udc_otg_priv.h header.
