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). Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> [matthijs@stdin.nl: Split patch from bigger patch, marked dwc2_module_params in pci.c as const and added commit message] Signed-off-by: Matthijs Kooijman <matthijs@stdin.nl> Acked-by: Paul Zimmerman <paulz@synopsys.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
