From a3d22a55cda99bcd151836f39ddd329af6cb1d30 Mon Sep 17 00:00:00 2001 From: Boris BREZILLON Date: Wed, 2 Sep 2015 10:30:25 +0200 Subject: [PATCH] mtd: nand: sunxi: rely on nand_dt_init initialization nand_dt_init(), called from nand_scan_ident(), is already parsing the generic MTD/NAND DT properties, and initializing the nand_chip struct accordingly. Rely on this initialization instead of manually parsing those properties.
