From 969e57adc2589a0a0ae5edbbe7b92062565ce70b Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Fri, 23 Dec 2011 17:27:46 +0200 Subject: mtd: mtdchar: rename functions We are going to re-work the MTD interface and change 'mtd->write()' to 'mtd_write()', 'mtd->read()' to 'mtd_read()' and so forth for all functions in the 'struct mtd_info' structure. However, mtdchar.c has its own 'mtd_read()', 'mtd_write()', etc functions which collide with our changes. This patch renames these functions to 'mtdchar_read()', 'mtdchar_write()', etc. Additionally, to make the 'mtdchar.c' file look consistent, rename similarly all the other functions starting with 'mtd_'.
