Subject: [PATCH 2/2] iommu/sun50i: Use __GFP_ZERO instead of memset()
Date: Thu, 14 May 2020 14:46:21 +0200	[thread overview]
Message-ID: <20200514124621.25999-2-joro@8bytes.org> (raw)
In-Reply-To: <20200514124621.25999-1-joro@8bytes.org>

From: Joerg Roedel <jroedel@suse.de>

Allocate zeroed memory so there is no need to memset it to 0 in the
driver.
