Subject: [Nouveau] [PATCH 03/14] dma-buf: Replace dma-buf-map with iosys-map
Date: Fri, 28 Jan 2022 00:36:15 -0800	[thread overview]
Message-ID: <20220128083626.3012259-4-lucas.demarchi@intel.com> (raw)
In-Reply-To: <20220128083626.3012259-1-lucas.demarchi@intel.com>

iosys-map is the new name for dma-buf-map and will gain new
capabitilities. Replace with the new API.
