From 1f330c3279004dd83fcbac5669a858366c51e058 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 20 Jan 2016 14:58:41 -0800 Subject: drivers/firmware/broadcom/bcm47xx_nvram.c: use __ioread32_copy() instead of open-coding Now that we have a generic library function for this, replace the open-coded instance.
