Subject: [RFC PATCH 14/15] hwrng: exynos - fixup IO accesors
Date: Wed, 8 Jun 2016 19:31:09 +0100 [thread overview]
Message-ID: <20160608183110.13851-15-matthew@mattleach.net> (raw)
In-Reply-To: <20160608183110.13851-1-matthew@mattleach.net>
From: Ben Dooks <ben.dooks@codethink.co.uk>
The __raw IO functions are not endian safe, so use the readl_relaxed
and writel_relaxed versions of these.
