From f226e652f6e8bdca5ce552ef1e0e8ec98bf8ce9a Mon Sep 17 00:00:00 2001 From: Yangbo Lu Date: Tue, 30 Jan 2018 20:45:25 +0800 Subject: [PATCH] layerscape: fix call trace of pfe module removing Updated pfe kernel patch to clean up iounmap(pfe->ddr_baseaddr). pfe->ddr_baseaddr was got through phys_to_virt() not ioremap(), so iounmap() for pfe->ddr_baseaddr should be removed.
