From 68d6a01bdd2a9ebae858271129d0a8d4ae865e93 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 12 Jun 2013 21:09:26 +0300 Subject: usb: dwc3: core: introduce and use macros for Event Size register That register has more than just the event buffer size; we can also mask and unmask that particular interrupter on bit 31 of that register. In this patch we introduce the necessary macros and make sure to use the new macros while also making sure we mask interrupts during driver removal.
