From 8261bd4e91e26d12c1ade9f94dae51629157c18b Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Thu, 6 Apr 2017 13:14:28 +0300 Subject: [PATCH] usb: dwc3: make macros safe to expression arguments We must make sure that our macros are safe against expressions passed as arguments. We have seen one problem where GTXFIFOSIZ(n) was failing when passed the expression (epnum >> 1) as argument. The problem was caused by operator precedence between >> and *. To make sure macros are safe, we just wrap argument with () when using it.
