Subject: [PATCH 4/5] iommu/sun50i: Fix flush size
Date: Thu, 13 Oct 2022 20:12:19 +0200 [thread overview]
Message-ID: <20221013181221.3247429-5-jernej.skrabec@gmail.com> (raw)
In-Reply-To: <20221013181221.3247429-1-jernej.skrabec@gmail.com>
Function sun50i_table_flush() takes number of entries as an argument,
not number of bytes. Fix that mistake in sun50i_dte_get_page_table().
Fixes: 4100b8c229b3 ("iommu: Add Allwinner H6 IOMMU driver")
