From 90dbceafe8d812bde318c29ac844e57fb71c9418 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Mon, 29 Apr 2013 19:49:08 +0000 Subject: [PATCH] staging: dwc2: add const to handling of dwc2_core_params Now the functions use proper const annotations, the global variable with default params can be marked const, which prevents these values from being changed for a specific device (in theory there could be multiple controllers with different settings, for example).
