From 68aa352de28235bccdcee96ddf49f7628e93ec6f Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Mon, 4 Mar 2013 16:05:00 +0200 Subject: [PATCH] mtd: nand: rename the id field of 'struct nand_flash_dev' The 'id' is a bit confusing name because NAND IDs are multi-byte. Re-name it to 'dev_id' to make it clear that this is the "device ID" part (the second byte). While on it, clean-up the commentary for 'struct nand_flash_dev'.
