From 348d56a8c6067f3b2f1799d6f050f3be4bf5904b Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Fri, 7 Sep 2018 00:38:48 +0200 Subject: mtd: rawnand: Keep all internal stuff private A lot of things defined in rawnand.h should not be exposed to NAND controller drivers and should only be shared by core files. Create the drivers/mtd/nand/raw/internals.h header to store such definitions, and move all private defs to this header. Also remove EXPORT_SYMBOLS() on functions that are not supposed to be exposed.
