From b616d9b0a708eb90eb474e1b6ec6dfe4c48a1678 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Mon, 30 May 2016 13:57:55 -0500 Subject: nand: Embed mtd_info in struct nand_chip nand_info[] is now an array of pointers, with the actual mtd_info instance embedded in struct nand_chip. This is in preparation for syncing the NAND code with Linux 4.6, which makes the same change to struct nand_chip. It's in a separate commit due to the large amount of changes required to accommodate the change to nand_info[].
