From 74add49f1b829dd580aae1dfdce2a0ebbbba216c Mon Sep 17 00:00:00 2001 From: Tobias Jakobi Date: Tue, 24 Feb 2015 15:20:46 +0100 Subject: [PATCH] exynos: introduce g2d_add_base_addr helper function In almost all functions the base address register is written, so it makes sense to have a helper function for this. v3: Wrap line as pointed out by Emil Velikov .
