From ecb42fea59cf2d1e7160c5c7e707120e0e6714db Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Wed, 13 Mar 2013 13:45:00 +0200 Subject: mtd: nand: use more reasonable integer types Use 'unsigned int' instead of 'unsigned long' in the NAND chip description data structure, because 32-bits is more than enough for our purposes. We do not need 64-bits, which is what we end up on 64-bit architectures. We declare many instances of this data structure, so this should help saving some amount of memory.
